Al-Ahli Arab Hospital explosion

Al-Ahli Arab Hospital explosion
On 17 October 2023, an explosion took place in the parking lot of the courtyard of al-Ahli Arab Hospital in Gaza City during the 2023 Israel–Hamas war, resulting in a large number of fatalities and injuries among displaced Palestinians seeking shelter there.
A few days prior to the incident, the hospital had received evacuation orders from Israel, and was hit by Israeli rocket fire, which damaged two floors and injured four staff members. The incident that followed caused a large explosion while many displaced Palestinians were taking refuge at the hospital. Reports of the number of fatalities vary widely, with the Hamas-run Gaza Health Ministry reporting 471 killed, and the Anglican diocese that manages the hospital reporting 200 people, while US intelligence agencies assessed a death toll between 100 and 300.
The cause of the explosion is contested. Israel, the United States, France, the United Kingdom, and Canada said that their intelligence sources indicate the cause of the explosion was a failed rocket launch from within Gaza by the Palestinian Islamic Jihad (PIJ), which has denied involvement. As of 23 October 2023 the consensus among independent analysts, while not a definitive conclusion, is that the explosion was caused by an errant rocket fired from within Gaza. Many news outlets have stated that the cause cannot be conclusively determined due to the lack of press access to Gaza and unavailability of the remnants of the projectile. The New York Times and The Washington Post have reported that a video pointed to by the Israel Defense Forces and others as evidence of what caused the explosion, in fact shows an Iron Dome projectile miles away from the hospital, and is unconnected to the hospital explosion.
Background
The Al-Ahli Arab Hospital is an 80-bed hospital in Gaza City. It was run by the Foreign Mission Board of the Southern Baptist Convention between 1954 and 1982, and is still known as the Baptist Hospital despite currently being under Anglican management.
Prior incidents
According to the World Health Organization, there were 51 attacks on health facilities in Gaza between 7 October and 17 October 2023, killing 15 hospital workers and injuring 27 others.
Before the explosion, there was also a history of Palestinian militant groups firing rockets from within the Gaza Strip that fell short of their target, resulting in property damage and casualties. According to the IDF, in the 11 days preceding the explosion at the Al-Ahli Hospital, 450 rockets fired by Palestinian militant organizations landed inside Gaza.
Incident on 14 October 2023
On Saturday 14 October, according to a statement by the Archbishop of Canterbury, Justin Welby, an Israeli rocket had damaged the upper two floors of the hospital's cancer treatment center, which contained the ultrasound and mammography wards, and injured four staff members. The Anglican Archbishop of Jerusalem described the cancer treatment centre as the "Crown Jewel of Ahli Hospital" that had provided cancer diagnoses as a prelude to treatment options at Ahli and other hospitals.
The Washington Post reported that an Anglican pastor working for the diocese had filmed a video of a shell in the hospital's ultrasound room and that the video showed a 155mm artillery illumination shell. The report said, "[i]llumination rounds are not fired directly at targets and descend on a parachute to signal, illuminate areas or mark targets, while the body of the shell falls from the sky". An Israeli military spokesman said, "If an artillery round landed there, then it was probably a result of it falling or landing after having been fired, but definitely not targeting the hospital."
Evacuation orders
The Anglican Diocese of Jerusalem stated the hospital had received at least three evacuation warnings from the Israeli military on Saturday, Sunday, and Monday.
In his statement on 15 October 2023 Archbishop of Canterbury, Justin Welby said, "The seriously ill and injured patients at the Anglican-run Ahli Hospitaland other healthcare facilities in northern Gazacannot be safely evacuated."
On Monday 16 October, Israel ordered the al-Ahli Arab Hospital, and the rest of northern Gaza, to evacuate. Because of insufficient beds in the southern Gaza Strip and no means of transporting patients, such as newborns in incubators or patients on ventilators, the evacuation orders were widely regarded as impossible to comply with.
The day of the explosion
Throughout Tuesday 17 October, Hamas published numerous posts on its Telegram channels providing updates on rocket attacks aimed at Israeli territory. An estimated 400 to 500 displaced Gazans were sheltering on hospital grounds from the ongoing 2023 Israel-Hamas war.
Explosion
The explosion occurred in a parking lot in the courtyard at 6:59 p.m. local time on Tuesday 17 October, creating orange plumes in the sky. A video captured the explosion's first sounds, described as a "whirring noise." Local reports of the explosion were made between 7 p.m. and 7:20 p.m.
The explosion did not cause significant damage to surrounding buildings. Scorch marks and fire-damaged vehicles, including one vehicle that was flipped over, were observed in the parking lot at the explosion site the following day. A crater at the impact site was described as "fairly shallow". French intelligence assessed the crater to be about long, across, and to deep. According to CNN, the impact crater was approximately by 3 ft wide, and deep.
Ghassan Abu Sittah, of Médecins Sans Frontières, said that the ceiling of the operating room collapsed.
The cause of the explosion has not been confirmed. Early efforts to analyse the Al-Ahli Arab Hospital explosion were quickly complicated by a variety of claims and counterclaims over who was responsible, as well as the rapid spread of unverified, misleading and false information on social media.
Casualties
The number of persons killed in the explosion has not been independently verified. As of 19 October 2023, the death toll reported by the Hamas-led Gaza Health Ministry was 471, revised from their initial report of 500. The board chair of the American Friends of the Episcopal Diocese of Jerusalem told a local ABC News station that the organization believes approximately 200 people died in the explosion. As of 19 October 2023, US intelligence agencies had assessed that the blast killed 100 to 300 people, and that the actual number was likely on the low end of that range.
Mohammed Abu Selmia, director of the nearby al-Shifa Hospital, estimated a death toll of 250 and reported that around 350 injured people were brought to his hospital by both ambulances and personal cars. He said the terrible condition of many bodies made it difficult to arrive at a total number of dead.
IDF spokesman Rear Admiral Daniel Hagari criticized media outlets for quickly disseminating what he termed as "unverified claims" by Hamas regarding the death toll, saying it was implausible for Hamas to accurately determine the casualty figures so soon after the incident.
Hamas declined to disclose any information about the identity of the deceased to The New York Times.
Munition debris
On 22 October 2023, Hamas declined a request by The New York Times to view any remnants of the object that had struck the parking lot. A Hamas spokesman said that it had "dissolved like salt in the water" and that nothing was left. A munitions expert interviewed by The New York Times contradicted Hamas's claim, indicating that recoverable debris should be present based on satellite imagery. Hamas told The Washington Post that it possessed remnants of the munition and that "they will soon be shown to the world," directly contradicting what was said to The New York Times.
Aftermath
Protests
The explosion sparked protests in a number of countries, including Canada, Egypt, Iran, Iraq, Jordan, Kuwait, Lebanon, Libya, Morocco, Qatar, Syria, Tunisia, Turkey, United Kingdom, and Yemen. In Ramallah and other cities in the West Bank, protestors chanted against Mahmoud Abbas and threw stones, leading to police using tear gas and stun grenades in an attempt to disperse protestors. Thousands of protestors marched outside the Israeli Consulate in Istanbul to protest against the war, and in Jordan, protestors attempted to storm the Israeli embassy. The US and French embassies in Beirut also faced protests aimed at their support for Israel.
Political fallout
Jordan canceled a quadrilateral summit that had been scheduled to take place between Jordanian King Abdullah II, President of the Palestinian National Authority Mahmoud Abbas, Egyptian President Abdel Fattah el-Sisi, and US President Joe Biden, after Abbas withdrew from it in protest of the explosion.
News coverage
News coverage of the event changed quickly, with conflicting reports from Gazan, Israeli and American sources. The Guardian initially reported that "the scale of the blast appeared to be outside either of the militant groups' capabilities." BBC correspondent Jon Donnison told BBC News viewers on the evening of the explosion: "It's hard to see what else this could be, really, given the size of the explosion, other than an Israeli air strike, or several air strikes", adding, "When we've seen rockets being fired out of Gaza, we never see explosions of that scale." Days later, BBC's deputy director of news Jonathan Munro said that the corporation had made a "mistake" in is live coverage, and that Donnison "was wrong to speculate about the cause of the explosion of the hospital." BBC also issued a clarification and apology on 23 October, writing: "We accept that even in this fast-moving situation it was wrong to speculate in this way about the possible causes and we apologise for this, although he did not at any point report that it was an Israeli strike."
After the explosion on 17 October, the New York Times' home page prominently featured headlines highlighting the Palestinian claims about an "Israeli Strike" and "At Least 500 Dead", before starting to tone them down and include Israeli counter-claims after about two hours (according to an analysis by Nieman Lab). Several New York Times journalists had raised concerns about these headlines internally, but they were overruled. On 23 October 2023, The New York Times published an Editors' Note (which Nieman Lab summarized as "a limited mea culpa") indicating that its early coverage of the event "relied too heavily on claims by Hamas, and did not make clear that those claims could not immediately be verified" and stated that "Times editors should have taken more care with the initial presentation, and been more explicit about what information could be verified."
On 25 October 2023, Le Monde published an explanation stating that they "were not cautious enough" in their initial coverage, which suggested that the Israeli army was responsible for the explosion and was not explicit in disclosing that the health ministry in the Gaza Strip is "administered by Hamas." The explanation noted that the inability to verify information because of the Israeli army's ban on press access to Gaza made cautious coverage especially important, and pledged to "regularly remind [its] readers that some news coming out of the Gaza Strip, in particular casualty figures, cannot be verified" and to clarify Hamas's control over the health ministry.
Analyses
The BBC noted on 26 October 2023 that the analyses since the explosion have focused on three main areas: the absence of any fragments from the munition, the crater and damage caused by the explosion, and images showing "a projectile rising over Gaza." To conduct a full investigation would require independent access to the site, inspection of any physical evidence, and the ability to interview witnesses–none of which has been possible because of the state of the ongoing war.
Origin and trajectory of munition
According to the video analysis of The Wall Street Journal, a long-range rocket was launched from Gaza in a northeastern direction toward Israel. Ten seconds after the rocket was launched, it malfunctioned and veered back toward the west, with the hospital in its path. The Wall Street Journal analysis also concluded that the impact crater was consistent with a rocket fragment incoming from the east.
On 20 October 2023, the Associated Press (AP) reported that it concluded from analyzing "more than a dozen videos from the moments before, during and after the hospital explosion, as well as satellite imagery and photos" that "the rocket that broke up in the air was fired from within Palestinian territory, and that the hospital explosion was most likely caused when part of that rocket crashed to the ground", while acknowledging the unavailability of definitive proof. AP reported that its preliminary conclusion was supported by experts in open-source intelligence, geolocation, and rocketry, "who all agreed the most likely scenario was a rocket from within Gaza that veered off and came apart seconds before the explosion." Andrea Richardson, an experienced war crimes investigator, told AP: "From the video evidence that I have seen, it’s very clear that the rockets came from within Gaza." Justin Crump, an intelligence consultant, said: "You can see obviously it fails in flight, it spins out and disintegrates, and the impacts on the ground follow that." Henry Schlottman, another intelligence expert, indicated that the most likely scenario based on available video evidence is that a rocket was launched within Gaza, failed mid-air, and accidentally struck the hospital.
Channel 4 News said that the trajectory of the missile that appeared on Al Jazeera Live is inconsistent with the missile launching location stated by the IDF and noted a contradiction in IDF statements on the location of the launching site of the alleged Palestinian missile that hit the hospital in their presentation. Channel 4 News also used Doppler effect sound analysis of the strike and visual analysis of the crater created by the strike. Both analyses indicated that the object that caused the blast would have come from points "east of the hospital not west as the IDF claimed." The New York Times, Bloomberg News, Al Jazeera, BBC News, and El País cited a tweet by Forensic Architecture, which the Times describe as critical of Israel, in which they disputed Israel's account that the blast was caused by a rocket from Gaza and instead was the result of a missile fired from the direction of Israel.
CNN consulted a leading American acoustic expert who spoke anonymously due to a lack of permission to speak publicly from the expert's university. The acoustic expert analyzed the sound waveform and concluded that although the changes in frequency indicated the projectile was in motion, no information could be gleaned regarding the direction of the motion. CNN also reported that the dark scorch marks on the "dark patches on the ground fanning out in a southwesterly direction from the crater," and burnt trees and a knocked-over lamppost behind the crater were consistent with a rocket approaching from the southwest. CNN noted that, if the projectile were an artillery munition, this could indicate a trajectory from the northeast, but the direction on impact would be inconclusive if the projectile malfunctioned and broke apart in the air. Markus Schiller, a missile expert who has provided analyses for NATO and the European Union, told CNN that he believed a malfunctioning rocket "fell apart mid-air" and crashed into the car park. He also said that it was not possible for him to confirm it with the "usual analysis drawing on altitude, flight path and the burn time" because it is not possible to predict the flight path and behavior of a malfunctioning rocket.
The New York Times published an analysis on 24 October 2023 casting doubt on the theory that the rocket seen in the al-Jazeera video had caused the explosion at the hospital. According to their analysis, some 25 seconds elapsed between the firing of the last Palestinian missile towards Israel and the explosion at the hospital. The al-Jazeera footage cited by the IDF as depicting a rocket aimed at Israel that exploded close to the time of the Al-Ahli Arab Hospital blast showed instead, the Times said, a rocket fired from an Israeli position near Nahal Oz that exploded on the border at a distance of some two miles from the hospital, making it unrelated to the blast. The Times analysis concluded that while responsibility for the hospital blast is unknown, the contention by Israeli and American intelligence agencies that a failed Palestinian rocket launch might have been to blame remains plausible. However, they added, "the Times analysis does cast doubt on one of the most-publicized pieces of evidence that Israeli officials have used to make their case and complicates the straightforward narrative they have put forth." In addition, the videos analyzed by the Times showed two things: firstly, that militants were firing dozens of rockets from southwest of the hospital, so a failed rocket falling well short of its target with unspent fuel might have caused the fiery explosion, and secondly, that there appears to have been Israeli bombardment in the area, with two explosions visible near the hospital within two minutes of it being struck. Israeli forces told The Times that they had not been striking "within a range that endangered the hospital," but gave no indication of how close the nearest strike had been.
The Washington Post published a similar analysis on 26 October 2023, which also concluded that the projectile shown in the videos is not the same projectile that caused the explosion at the hospital. Instead, The Washington Post concluded that the projectile seen in the videos appears to be an Israeli missile intercepting a rocket over Israeli territory about three miles from the hospital.
Rocket vs airstrike
The Washington Post consulted over two dozen munitions experts, all of whom agreed that the impact of the explosion was inconsistent with an airstrike, which would have caused greater destruction, or an artillery strike, "which would have left substantial fragments and probably not caused the massive fireball seen in videos."
BBC Verify spoke to a number of experts to establish whether publicly available evidence could establish the cause of the explosion. Some experts said they could not form a view on what occurred, while three experts said that the evidence was inconsistent with an Israeli airstrike or warhead damage, and that evidence was consistent with an explosion caused by rocket fuel. Security experts said that the preliminary evidence suggests that a Palestinian rocket fired inside Gaza caused the explosion.
Justin Bronk at Royal United Services Institute said that, while not conclusive, "a rocket failure causing an explosion and fuel fire" was a more likely explanation than an Israeli airstrike. Independent open-source intelligence (OSINT) groups and analysts interviewed by The Telegraph, including Evan Hill, an OSINT investigator for The Washington Post, as well as The Independent, agreed. The Wall Street Journal reported that analysts who examined publicly available images said the explosion site did not "bear the hallmarks of a strike with a bomb or missile of the types used by Israel" and that the "damage appeared more consistent with a fireball from a rocket."
The Guardian quoted Marc Garlasco as saying that the crater at the blast site required kinetic energy inconsistent with a Joint Direct Attack Munition (JDAM) aerial bomb, and was also inconsistent with an airstrike, concluding that it was "more likely to be a weapon that failed and released its payload over a wide area." In an interview with PBS, Garlasco also referred to an unusual amount of fire damage, pointing to a long period of burn which, according to him, is also inconsistent with the way standard military munitions work. Bellingcat noted that one of the images the IDF spokesman used to demonstrate there was no crater did in fact show what appeared to be a crater, and also quoted Garlasco's analysis. They requested comments and the next day IDF spokesman Jonathan Conricus stated that the size of the crater and the damage caused were too small for the munitions used by the IDF, as previously stated: "Scroll through pictures of rockets that impacted in Sderot, Ashkelon, in Be'er-Sheva, you'll see very similar sites," he said. "A small crater, lots of soot and fire remarks and you can see that all of the buildings around are generally intact." NR Jenzen-Jones, a director at Armament Research Services, also told the BBC that the crater observed at the hospital was significantly smaller than what would typically result from a 155 mm artillery projectile. On the other hand, Mark Cancian of the Centre for Strategic and International Studies said that he was unable to conclude from the available evidence whether the crater may have been caused by an artillery shell, a mortar, or a rocket.
Two researchers from the Australian Strategic Policy Institute noted that the blast radius and lack of structural damage on the surrounding cars were inconsistent with a typical Israeli airstrike.
The Associated Press noted the absence of any large crater of the sort that would be expected if the explosion were caused by an Israeli airstrike. Although Israel does have smaller munitions in its arsenal, the AP noted that "there has been no public evidence of such missile strikes in the area around the al-Ahli Arab Hospital on Tuesday night." AP reported that David Shank, a retired US Army colonel with expertise in military rockets and missiles, explained that the large explosion and subsequent fire was likely caused by the fact that the rocket was still full of propellant. A later analysis by the AP, including video evidence and satellite imagery, as well as expert opinion, assessed that a rocket was fired from Gaza, and that "the hospital explosion was most likely caused when part of that rocket crashed to the ground", though the lack of physical evidence makes definitive proof unlikely if not impossible.
reported that the opinion of Fabian Hoffman, a weapons researcher at the University of Oslo, is that the most likely explanation regarding the cause of the explosion is that a rocket fell apart in several phases and hit the hospital. According to , Hoffman could not say for sure what caused the rocket's failure, but he suspected that the engine overheated, causing the rocket to fall to the ground.
Agence France-Presse (AFP) published an article on 20 October 2023, reporting on interviews of several analysts, who "remained cautious, preferring not to rule out any scenario." Heloise Fayet, a researcher at the French Institute of International Relations, said that it was difficult to link the minor damage observed at the hospital with the large explosion seen on video. Based on the nature and extent of the damages, Fayet concluded that the most likely scenario was that a rocket hit the gas tanks of several cars. The same AFP article quoted Joseph Henrotin, editor-in-chief of the journal Defense and International Security (DSI), as saying that the visible damage was "consistent with the hypothesis of engine pieces, for example, of a rocket, which fall in a ballistic alignment, projecting debris, flaming materials, and creating a blast effect," at the same time noting that the absence of any structural damage to the building, the impact site being in the parking lot, and the size of the craters were all inconsistent with "the ammunition and targeting capabilities available to the Israelis". Similarly, Xavier Tytelman, an air defense consultant who also works for the magazine Air & Cosmos, said that the grade of munitions used by Israel, which frequently destroy entire buildings with a single strike, "would have done infinitely more damage" than that seen in the hospital parking lot, noting that the images of the scene were not comparable to the effects of laser-equipped JDAM bombs. Tytelman was also quoted as suggesting the rocket in question was likely an Iranian-designed Badr-3 and that its trajectory change was caused by faulty detachment of the first stage. The analysts interviewed by AFP stated that they could not completely rule out the scenario of a micro munition fired from an Israeli drone, at the same time observing that they were not aware of any evidence to support it.
CNN's investigative report from 21 October 2023, suggests that a rocket launched from Gaza malfunctioned mid-air, causing the explosion at a hospital complex. Experts consulted found the damage inconsistent with an Israeli airstrike. Missile expert Markus Schiller hypothesized that the rocket broke apart mid-air and ignited fuel at the hospital's car park, causing the explosion. Both Cedric Leighton, former National Security Agency of US deputy director, and Chad Ohlandt, a senior engineer at Rand Corporation, concurred. Analysis of mobile phone-captured audio also did not align with a high-grade military explosion. The experts noted a smaller impact crater and lack of wide destruction, undermining the possibility of an aircraft bomb. Patrick Senft from ARES and an unnamed explosives specialist emphasized that the damage was more likely caused by the rocket's fuel and shrapnel, rather than an artillery shell. All cautioned that definitive conclusions couldn't be made due to various limitations.
The Wall Street Journal published a report on 21 October 2023 containing an analysis of four geolocated and verified videos of the incident, concluding that the explosion was caused by a misfired rocket.
Channel 4 News noted that the explosion site contained only small craters, that buildings surrounding the explosion site were only superficially damaged (and did not structurally collapse), and some of the windows of a nearby church were undamaged–all facts that made it unlikely that the cause of the explosion was a ground-detonating Israeli missile strike, without ruling out the possibility of an air-burst explosion. Channel 4 also observed that although Palestinian Islamic Jihad had indicated they had recovered a warhead, they have not produced it.
India Todays OSINT Team analyzed the footage and images of the explosion and the aftermath as well as comparing the explosion site to previous aerial bombings by Israel. India Today reported on 18 October that the visual evidence does not match previous aerial bombings by Israel but that a more detailed investigation would be needed for a conclusive verdict.
Numerous other news outlets reported on similar opinions from experts they spoke with–all agreeing that the cause of the explosion was more likely a misfired rocket than an Israeli airstrike. According to NPR, as of 19 October 2023, the majority of independent researchers conclude that the damage is not consistent with a standard Israeli air strike.
Iron Dome
After the explosion, there was speculation on social media that Israel's Iron Dome air defense system could have played a role in causing the event. relayed the analysis of weapons expert Fabian Hoffman, of the University of Oslo, who noted that the Iron Dome is not designed to intercept rockets during their ascent. Similarly, the Associated Press cited to the opinion of John Erath, senior policy director at the Center for Arms Control and an expert on missile defense, who also relayed that the Iron Dome is designed to intercept rockets during their downward path into Israeli territory—not while they are in an upward trajectory—though Erath conceded that it is not technically impossible for Iron Dome to destroy a rocket during its ascent. Retired US Army colonel David Shank, an expert in missiles, concurred with this view, telling the Associated Press that the air defense system is generally not engaged unless a rocket has a high probability of causing casualties or damage within Israel, and would not likely be used to destroy a rocket flying over Gaza. Experts consulted by CNN found no evidence that the Iron Dome intercepted the projectile that caused the explosion.
Al Jazeera published an analysis of the hospital explosion on 19 October. Al Jazeera said they had constructed a second-by-second timeline by analyzing video footage of the event. According to Al Jazeera, a rocket launched from Gaza was intercepted by an Iron Dome interceptor and "completely destroyed" in mid-air five seconds prior to the hospital explosion. As no more rocket launches could be seen in video footage from Gaza from this time until the hospital explosion, Al Jazeera said that they found "no grounds" for the IDF assertion that the hospital explosion was caused by a failed rocket launch from Gaza. The investigation also identified "four Israeli air strikes on Gaza, targeting the area near the hospital" in the minutes before the explosion. Uzi Rubin, the founder and first director of the Israel Missile Defense Organization, told the BBC that the video footage is not consistent with an Iron Dome interception, which causes "an almost immediate sympathetic explosion of the hostile rocket warhead" as opposed to the "elongated glowing debris cloud that fades out after a couple of seconds" seen in the video. By contrast, Marc Garlasco said he did believe the video was consistent with an Iron Dome interception.
Death toll
The death toll asserted by the Gazan Health Ministry was not independently verified as of 18 October. The Wall Street Journal reported that open-source intelligence analyst Blake Spendley estimated the death toll at 50, based on his review of videos and photos of the scene. Several analysts cast doubt on the death toll figure from the Gazan Health Ministry, citing the limited shock-wave damage and the small size of the open area. On 19 October, Agence France-Presse cited an unnamed senior European intelligence official who said he believed the death toll was no more than 50. A video geolocated by Bellingcat showed "[a]t least two dozen bodies" in a grassy area near the explosion.
The New York Times, after reviewing video footage and witness accounts, said on 18 October that there were "scores" of bodies in the hospital's courtyard and the number of casualties was "high".
The general director of Gaza's Al-Shifa Hospital, which took in victims of the blast, estimated the death toll at 250, and journalist David Zweig argued that media reports of the Gaza Health Ministry claiming 500 deaths were in fact based on a mistranslation of an official listing the total casualties (including injured survivors).
Authenticity of purported call recording
Shortly after the explosion, IDF released an audio recording purportedly containing an intercepted conversation between two Hamas operatives saying that a misfired rocket launched by PIJ caused the explosion. BBC Verify and CNN said they could not verify the recording. Channel 4 News reported on a forensic analysis of the alleged Hamas operative audio released by the IDF, concluding that it was digitally manipulated. Channel 4 News spoke to two unnamed Arab journalists who said that the recording did not appear authentic, because the "language, accent, dialect, syntax and tone" were not credible. Channel 4 News also reported on a preliminary audio assessment performed by a sonic analysis company called Earshot, which concluded that the audio recording had been edited to fuse two channels that were recorded separately, one for each speaker. Voice of America and NBC News quote a US intelligence official who said that their conclusions regarding the cause of the explosion were based in part on another audio recording, different from the publicly available one and assessed as authentic by language experts.
Governments and other entities
Israel
The Israeli Defense Forces said the cause of the blast was a misfired rocket targeting the Israeli city of Haifa and launched by Palestinian Islamic Jihad (PIJ), a Palestinian militant group allied with Hamas. Rear Admiral Daniel Hagari of the IDF Spokesperson's Unit said that intelligence indicated that PIJ had launched a barrage of rockets near the hospital, and shared drone-collected aerial photography that he said was inconsistent with Israeli munitions.
The IDF also published audio that it says contains intercepted discussions among militants saying that their misfired rocket caused the explosion. BBC Verify said that it could not verify the recording.
On 18 October, the IDF released drone footage, which it said showed the hospital before and after the explosion. The annotated video showed burned vehicles in the hospital parking lot, and noted the apparent lack of a crater or significant structural damage to surrounding buildings. The IDF said these attributes were inconsistent with the aftermath of Israeli munition strikes.
Following the explosion, the official Israel Twitter account published a statement saying that the attack was the result of an enemy rocket. Attached to the tweet was footage, purported to be proof of the rocket coming from Gaza. Aric Toler, a journalist on the visual investigations team of the The New York Times, noted that the timestamps on the video were at least 40 minutes after the explosion was known to have occurred. Shortly after, the Israeli government Twitter account edited the tweet, removing the video from it. The IDF said it was not involved with the video, and attributed it to the Israeli Ministry of Foreign Affairs.
According to the The New York Times, Israel has declined its requests to share logs of its military activity in the area at the time of the explosion or say what video it was basing its assessment that a failed Palestinian rocket launch was responsible for the blast on.
Hamas and Palestinian Islamic Jihad
The Gaza Health Ministry said the explosion was caused by an Israeli airstrike. Palestinian Islamic Jihad has denied responsibility, blaming Israel for the explosion and drawing attention to the fact that Israel had also hit the hospital on 14 October and previously ordered its evacuation. Hamas stated that Israel struck the hospital as punishment for the failure to evacuate.
David Leonhardt of The New York Times wrote on 20 October that "Gaza officials and their supporters have three main arguments, all circumstantial":
First, Palestinians have noted that the al-Ahli Arab Hospital was hit by rocket fire three days earlier, although according to The New York Times, the source of the rocket fire remains unclear, and staff had received text messages and phone calls demanding that the hospital be evacuated. Anglican Archbishop Hosam Naoum said the Israeli military had telephoned and texted the hospital at least three times since 14 October, asking patients and staff to leave. He said these warnings were specific to the hospital, and not part of Israel's general push to have civilians leave northern Gaza: "There were specific warnings to get out of the building."
Second, Israel dissembled about civilian casualties before, such as in the death of Palestinian-American journalist Shireen Abu Akleh.
Third, Israeli government officials have put out inconsistent information regarding the hospital explosion, including a video of a rocket barrage showing a time stamp well after the time of the explosion. Hananya Naftali is frequently cited on this point. Naftali, an Israeli social media influencer and a social media advisor to Netanyahu, initially posted a statement on X, stating the Israeli Air Force had struck a Hamas terrorist base inside a hospital. Naftali promptly deleted this, later stating that his previous post was a false assumption he had made based on a Reuters report. PolitiFact found no evidence of Naftali being "an official spokesperson for Israel or its military". PolitiFact also noted, "He said in an Oct. 14 Facebook video that Netanyahu assigned him to a task force to defend Israel in the media."
Hamas failed to produce or describe any evidence linking Israel to the explosion. Islamic Jihad claimed to have a missile fragment, but have not produced it." Ghazi Hamad, a Hamas spokesperson, told the Associated Press that Hamas would welcome a United Nations investigation of the cause of the explosion. He told the New York Times on 22 October that the munition was not available for inspection because it had "dissolved like salt in the water. It’s vaporized. Nothing is left". N.R. Jenzen-Jones, director of the Australia-based Armament Research Services, said that "[o]ne would expect remnants to be recoverable in all but the most extreme circumstances, and the available imagery of the hospital site suggests something ought to be identifiable on the ground[.]" The BBC noted that, in photographs taken in the moments following the explosion, Hamas-affiliated security forces with clothing bearing logos of the Palestinian police's Explosive Ordnance Disposal Unit could be seen inspecting the point of impact. An expert consulted by the BBC said that it would be highly unusual for there to be no debris left behind by such an explosion.
United States
US President Joe Biden supported the Israeli account of events, and referred to Pentagon intelligence sources that indicate the explosion was caused by a Palestinian Islamic Jihad (PIJ) rocket misfire.
US officials said that the US had collected "high confidence" signals intelligence indicating that PIJ was responsible. Adrienne Watson, a spokesperson for the United States National Security Council, said, "While we continue to collect information, our current assessment, based on analysis of overhead imagery, intercepts and open-source information, is that Israel is not responsible for the explosion at the hospital in Gaza yesterday." Other US intelligence officials concurred, adding the analysis was still preliminary and investigations would continue.
Blake Spendley of CNA said on 18 October that "At the moment, the preponderance of evidence does point to it being a Hamas or PIJ rocket hitting the area."
On 24 October 2023, US intelligence officials briefed reporters or the New York Times, NBC News, and other US media, including on the intelligence community's assessment of the explosion on condition of anonymity. The New York Times reported that Palestinian communications intercepted by Israel and publicly available video gave the intelligence community high confidence that a rocket launched from Gaza experienced a "catastrophic motor failure," causing the warhead to fall near the hospital. The officials said their analysis focused primarily on the Al Jazeera video that captured the moment of the explosion during a live broadcast, though they also considered signals intelligence and images of the aftermath of the explosion. They further said that their assessment was also based on the absence of any Israeli weapon presented by Palestinians at the site of the explosion. According to the US officials, the videos showing the fireball and fire-damaged vehicles in the hospital parking lot are consistent with a malfunctioning missile. The officials also told the Times that they had authenticated communications intercepts provided by Israeli intelligence, all of which consisted of Hamas members "discussing their belief that the explosion was caused by an errant or malfunctioning rocket fired by Palestinian Islamic Jihad." The officials also told the Times that they had low confidence in their assessment of a death toll between 100 and 300, noting that an accurate figure was impossible to confirm because of the absence of independent sources. The Washington Post reported that the US intelligence community had determined with "high confidence" that the cause of the explosion was not an Israeli airstrike and, "absent other points of information and supporting material", with "low confidence" that Palestinian fighters were responsible for the rocket that struck the parking lot. NBC News quoted an intelligence official who said that the intelligence community "assessed with high confidence that Israel was not responsible for the explosion at the hospital and that Palestinian militants were responsible" and that they assessed with low confidence that Palestine Islamic Jihad had launched the rocket.
France
France's Directorate of Military Intelligence stated that a misfired rocket from within Gaza was the "most probable cause". A French military official who spoke with Associated Press on condition of anonymity stated that French intelligence drew this conclusion from classified information, satellite imagery, intelligence shared by other countries, and open-source information. The official stated that the blast crater was indicative of an explosive charge of approximately 5 kilograms, which is consistent with several types of rockets used by Palestinian militant groups. With regard to the origin of the rocket, the French official said that the impact hole suggested the projectile was on a south-to-north trajectory. In addition, the French military intelligence official indicated that, while he could not say for certain, the reported death toll of 471 did not seem possible based on the apparent size of the rocket.
Canada
, Canada had refrained from taking a position regarding the cause of the explosion. Prime Minister Justin Trudeau said that Canadian officials "saw some preliminary evidence," but would continue to work with allies "before reaching any firm and final conclusion." On 21 October, Canada's Department of National Defence announced that an independent analysis conducted by Canadian Forces Intelligence Command had determined "with a high degree of confidence that Israel did not strike the hospital on October 17, 2023," and that the more likely cause was an errant rocket fired from inside Gaza. The assessment was based on open source intelligence and classified reporting.
United Kingdom
Rishi Sunak, the UK Prime Minister, told the House of Commons that, relying on British intelligence agencies, the government had concluded that the blast was likely the result of a Palestinian rocket fired towards Israel. He also criticized the initial reporting, saying it had a negative impact on the region.
Italy
Antonio Tajani, Italy's Foreign Minister, said on 24 October 2023 that the cause of the explosion was not an Israeli missile and that the death toll was around 50. He did not indicate what evidence formed the basis of his comments.
Calls for international investigation
On 19 October 2023, during a State Department daily briefing, US Department of State spokesperson Matthew Miller, indicated that he did not believe an international investigation into the explosion was "appropriate at this time" given the fact that Israel had provided evidence to support its claims, whereas Hamas had provided none.
On 20 October 2023, the United Nations Human Rights Office called for an independent investigation into the explosion. A spokesperson for the office stated that there was a need for accountability and observed that it would be difficult for the UN to monitor an investigation because of the ongoing conflict between Israel and Hamas.
Reactions
Palestinian Authority President Mahmoud Abbas declared three days of mourning following the deadly event and canceled a planned meeting with US President Joe Biden. Biden said that he was "outraged and deeply saddened by the explosion", but he did not immediately attribute blame for the incident, saying instead that the US would investigate the event. Canadian Prime Minister Justin Trudeau described the explosion as "horrible" and "unacceptable", but did not assign blame. The Director-General of the World Health Organization, Tedros Adhanom Ghebreyesus, condemned the alleged attack. The secretary-general of the United Nations, António Guterres, said that he was "horrified by the killing of hundreds of Palestinian civilians in a strike on a hospital". UN human rights chief, Volker Türk, condemned the "totally unacceptable" and "horrific" strike and demanded accountability. Médecins Sans Frontières said it was "horrified" by the "recent bombing", and called it a "massacre." The Red Cross was "shocked and horrified" by the reports. Indian Prime Minister Narendra Modi conveyed condolences to President Mahmoud Abbas.
Israeli President Isaac Herzog condemned Palestinian Islamic Jihad, writing, "Shame on the vile terrorists in Gaza who wilfully spill the blood of the innocent." Herzog said that accusations that Israel caused the blast were "a 21st-century blood libel."
Hezbollah said the blast was an Israeli "massacre" and called for a "day of rage" on 18 October against Israel and Biden's pending visit to the Middle East. Egypt, Iran, Iraq, Jordan, and Turkey also condemned the alleged attack, while Qatar condemned what they described as "a dangerous escalation". Saudi Arabia condemned "the forces of the occupation" for the alleged attack, which it described as a "heinous crime". Russia and the United Arab Emirates called for an urgent meeting of the UN Security Council. The King of Jordan, Abdullah II, said that the Middle East was "on the brink of falling into the abyss" amid fears that the conflict could escalate into a wider war involving other armed groups. Iranian President Ebrahim Raisi promised a "harsh response" to what happened. Turkey also declared three days of mourning for the victims of the explosion.
Without providing any evidence, the foreign ministry of North Korea accused Israel of bombing the hospital "under the undisguised patronage of the United States" and alleged that the United States was guilty of "giving Israel a green light to massacre Palestinians without any worries."
On culpability
Biden subsequently said at a meeting with Israeli Prime Minister Benjamin Netanyahu that, "Based on what I've seen, it appears as though it was done by the other team, not you", later adding "I'm not suggesting that Hamas deliberately did it, eitherit's that old thing: You've got to learn how to shoot straight".
Saudi Arabia, Jordan, Qatar, UAE, Bahrain, Oman, Egypt, Lebanon, Algeria and Libya condemned the explosions as attacks, and accused Israeli forces of bombing the hospital. The UAE and Bahrain condemned the explosions as Israeli attacks, and demanded an "immediate cessation of hostilities". The Turkish President Recep Tayyip Erdogan denounced the bombing as "the latest example of Israeli attacks devoid of the most basic human values." Moussa Faki, Chairperson of the African Union Commission, denounced the IDF attack as a "war crime" and demanded that other countries stop what they said was Israeli aggression.
Caretaker Prime Minister Anwaar-ul-Haq Kakar and the Ministry of Foreign Affairs of Pakistan condemned the IDF as the perpetrators of the attack. They described the attack as "inhumane and indefensible" and asserted that IDF targeting of civilians and medical personnel were "war crimes". Kakar denounced IDF military operations as a "campaign of terror"; and the Foreign Ministry demanded global action to swiftly stop "Israeli bombardment and siege of Gaza".
