"A Syrian warplane belonging to the Syrian regime was brought down when targeted by fighters from the Islamic State in the city of Deir al-Zor," Amaq said in an online statement.

The Syrian Observatory for Human Rights, which monitors the Syrian conflict now in its sixth year, said the pilot of the MiG Syrian warplane was killed.

The Observatory said the plane came down in the Jebel Tharda area which overlooks the government's Deir al Zor military airport.

Jebel Tharda is where on Saturday U.S.-led coalition air strikes reportedly killed dozens of Syrian soldiers, endangering a U.S.-Russian brokered ceasefire and prompting an emergency U.N. Security Council meeting as tensions between Moscow and Washington escalated.

The city's airport and some government-held districts have been entirely surrounded by Islamic State since last year, with the airport providing the only external access.

Intense air strikes over the past 24 hours have hit Islamic State controlled areas near Deir al Zor city, the Observatory and Syrian state media said. </s> ISIL fighters shot down a Syrian military plane in the eastern Syrian city of Deir Az Zor, the group's Amaq news agency reported on Sunday.

"A Syrian warplane belonging to the Syrian regime was brought down when targeted by fighters from the Islamic State in the city of Deir al-Zor," Amaq said in an online statement.

US air raid on Syrian army post sparks Russia tension

Earlier in the day, Syrian state news agency SANA reported that government troops had regained territory in the eastern province lost to fighters affiliated with the Islamic State of Iraq and the Levant (ISIL, also known as ISIS) "as a result of the American aircraft aggression".

The US military said it may have unintentionally struck Syrian troops while carrying out a raid against ISIL in Deir Az Zor on Saturday.

Russia's military said it was told by the Syrian army that at least 62 soldiers were killed and more than 100 wounded in the raid in the Jabal Tharda area of Deir Az Zor.

The Observatory said on Sunday the plane came down in the same area, which overlooks the government's Deir Az Zor military airport.

The city's airport and some government-held districts have been entirely surrounded by ISIL since last year, with the airport providing the only external access.

Heavy air strikes over the past 24 hours have hit ISIL-controlled areas near Deir Az Zor city, according to the Observatory and Syrian state media. </s> US-led coalition aircraft hit a Syrian army position in the country's east on Saturday, according to an armed forces statement carried by the state news agency SANA.

"Warplanes from the American coalition hit one of the Syrian army's positions... near the Deir Ezzor airport," the statement said, adding that there were "casualties" but without giving a number.

The Russian army said 60 Syrian soldiers were killed in US-led coalition strikes.

The Syrian Observatory for Human Rights monitoring group said at least 30 soldiers were killed in the raids, but could not specify who carried them out.

Syria's army has been fighting off a fierce offensive by the Islamic State jihadist group on the Deir Ezzor military airport since last year.

"This is a dangerous and bold attack against the Syrian state and army, and clear evidence that the United States and its allies support the terrorist group Daesh," the statement said, referring to IS.

A Syrian military source also told AFP that US-led coalition strikes hit an army position in Jabal Therdeh, near Deir Ezzor military airport.

Under a fragile truce deal negotiated by the United States and Russia, fighting in Syria is to halt on all fronts across the country except those held by IS.

The US-led coalition has been carrying out raids against IS for two years in both Syria and Iraq. </s> (IraqiNews.com) Baghdad – ISIS confirmed on Sunday about shooting down a Syrian warplane in Deir al-Zour in eastern Syria.

Media reports, quoting ISIS news affiliate al-Amaq, said, “A fighter jet belonging to the Syrian forces was downed by ISIS in Deir al-Zour.”

The Syrian Observatory for Human Rights said, “The pilot of the Syrian fighter jet died, indicating that the plane was shot down in Tharde Mount area southern Deir Ezzor air base.”

The Observatory had earlier reported of intense air strikes during the last 24 near Deir ez-Zor. </s> Islamic State shot down a Syrian military plane in the eastern Syrian city of Deir al-Zor, the Islamic State-affiliated news agency Amaq said on Sunday.

“A Syrian warplane belonging to the Syrian regime was brought down when targeted by fighters from the Islamic State in the city of Deir al-Zor,” Amaq said in an online statement.

The Syrian Observatory for Human Rights, which monitors the Syrian conflict now in its sixth year, said the pilot of the MIG Syrian warplane was killed. </s> Syrian army says U.S.-led coalition jets bombed it in support of Islamic State

BEIRUT, Sept 17 (Reuters) - Syria's army general command said warplanes from the U.S.-led coalition bombed a Syrian army position at Jebel Tharda near Deir al-Zor airport on Saturday, paving the way for Islamic State fighters to overun it.

The air strike killed Syrian soldiers and was "conclusive evidence" that the U.S. and its allies support the jihadist group, the Syrian army said in a statement, noting that the strike was "dangerous and blatant aggression".

The U.S.-led coalition has been conducting air strikes against Islamic State since September 2014. In December Damascus accused the coalition of striking an army camp near Deir al-Zor, but Washington said it was done by Russian jets.

A strike list issued by the U.S. on Saturday said it had carried out a strike at Deir al-Zor against five Islamic State supply routes, as well as strikes near Raqqa and elsewhere in Syria.

Syria's army controls Deir al-Zor airport and parts of the city which are otherwise entirely surrounded by territory held by Islamic State.

The United States and Russia agreed a deal on Syria last week, involving a ceasefire which came into effect on Monday, aid deliveries to besieged areas and eventual joint targeting of militant jihadist groups if the truce works out.

Syria's five-year civil war between President Bashar al-Assad and rebels seeking to topple him has drawn in regional and global powers and allowed militant jihadist groups including Islamic State to gain territory and inspire attacks. (Reporting by Angus McDowall; Editing by Louise Ireland) </s> Australia has said its warplanes took part in US-led air strikes in eastern Syria that mistakenly killed Syrian army troops in an incident threatening to wreck an already tenuous ceasefire before it is a week old.

Russia’s military said it was told by the Syrian army that at least 62 soldiers were killed in the attack on a government position near Deir ez-Zour, with more than 100 wounded. The Syrian Observatory for Human Rights said at least 90 soldiers were killed.

The first air strikes on Aleppo since the ceasefire began last Monday evening were reported on Sunday.

An Australian defence department statement said its jets had targeted fighters they thought to be members of Islamic State, the jihadist faction also known as Isis.

“Overnight, coalition aircraft were conducting air strikes in eastern Syria against what was believed to be a Daesh [Islamic State] fighting position that the coalition had been tracking for some time,” the statement said.

“However, shortly after the bombing commenced, Russian officials advised the Combined Air Operations Centre that the targets may have been Syrian military personnel.

“While Syria remains a dynamic and complex operating environment, Australia would never intentionally target a known Syrian military unit or actively support [Islamic State],” it said, offering condolences to the families of the dead and pledging to co-operate with a US inquiry.

The US has also offered condolences and insisted the air strikes were a mistake. It said it had targeted Tharda mountain where a Syrian government offensive was seeking to capture Islamic State positions overlooking the Deir ez-Zour military airport.

Damascus claimed it had succeeded in taking Tharda despite the US bombing, and rejected Washington’s insistence that it hit Syrian troops in error. A foreign ministry statement said Syrian positions had been repeatedly attacked in strikes that were “on purpose and planned in advance”.

Russia warned that the incident puts a “very big question mark” over the future of a precarious ceasefire agreed by Washington and Moscow, and a strongly worded foreign ministry statement on Sunday said the strikes were “on the boundary between criminal negligence and direct connivance with Islamic State terrorists”.

It said the incident was a result of Washington’s “stubborn refusal” to co-operate with Moscow in fighting Isis, the al-Nusra Front – now renamed Jabhat Fateh al Sham – and “other terrorist groups”. </s> Beirut: Syrian warplanes carried out air strikes on Saturday against Islamic State in an area of countryside east of Raqqa and close to where U.S.-backed forces operate, Syrian state TV reported, citing a military source.

The attacks in the town of Maadan and village of Bir al-Sabkhawi, near the provincial boundary with Deir al-Zor governorate, "destroyed several bases and vehicles" belonging to the Islamist group, the source said.

The British-based Syrian Observatory for Human Rights monitoring group said it was the first time in several weeks that the Syrian military had launched an attack in that area.

The Syrian army has active front lines with Islamic State in Raqqa`s western countryside, where it has recaptured territory from the jihadists.

But air strikes in the east take the fight closer to where the U.S.-backed Syrian Democratic Forces (SDF), an alliance dominated by Kurdish fighters, are operating.

The SDF launched a final assault to drive Islamic State out of its stronghold of Raqqa city last month, and have spearheaded efforts against the group in Syria`s northeast.

The Syrian army backed by Russian warplanes is separately fighting the jihadists further west, but has also carried out air raids in Raqqa and Deir al-Zor provinces.

The SDF accused Syrian government forces of bombing their positions in June, one of several incidents that raised tension between the United States on one side and Syria and Russia on the other.

It was not immediately clear how close Saturday`s air strikes came to SDF positions, but they were within kilometres (miles) of SDF-controlled territory. </s> Syria’s army general command has said that US-led coalition jets bombed Syrian government forces’ positions near the eastern city of Deir ez-Zor

According to Syria’s official news agency SANA, warplanes from the U.S.-led coalition, supposedly fighting ISIS, bombed a Syrian army position at Jebel Tharda near Deir al-Zor military airport at 5 p.m. (1400 GMT) on Saturday.

The air strike killed Syrian soldiers who had been preparing for an attack against ISIS, and was “conclusive evidence” that the U.S. and its allies support the terrorist group, the Syrian army said in a statement

Sixty-two Syrian soldiers were killed and over 100 injured in the airstrike by the US-led coalition, Russia’s Defense Ministry spokesman, Major-General Igor Konashenkov, said, citing information received from the Syrian General Command.

The Russian Defense Ministry said on Saturday that the aircraft which carried out the bombings had entered Syrian airspace from the territory of Iraq. The airstrike against Syrian positions was performed by two F-16 jet fighters and two A-10 support aircraft, it said.

Even if the bombardment of the Syrian government troops was a mistake, it’s still a consequence of Washington’s unwillingness to coordinate its anti-terror efforts with Moscow, the ministry said.

The Defense Ministry also confirmed a report by SANA that an Islamic State offensive began right after Syrian Army positions were hit from the air.

The actions of the coalition “clearly paved the way for Islamic State (IS, formerly ISIS/ISIL) terrorists to attack the position and take control of it,” the agency said citing the General Command of the Army and Armed Forces.

The General Command has called the bombing a “serious and blatant aggression” against Syrian forces, and said it was “conclusive evidence” that the US and its allies support IS militants.

Earlier on Saturday, Russia accused the US of being reluctant to take measures to force rebels under its control to fall in line with the terms of the Syrian ceasefire.

Numerous Russian appeals to the American side remain unanswered, which “raises doubts over the US’s ability to influence opposition groups under their control and their willingness to further ensure the implementation of the Geneva agreements,” senior Russian General Staff official, Viktor Poznikhir, said.

Poznikhir also said that the truce is being used by the militants to regroup, resupply and prepare an offensive against government troops.
The United States acknowledges that its warplanes may have hit a Syrian Army position near Deir ez-Zor Airport in eastern Syria, while conducting an operation against ISIL, killing more than 60 Syrian troops.
