Example Input: Oceanside, New York (CNN) -- Deployed to a volatile outpost in southern Afghanistan where U.S. Marines routinely face a mix of skirmishes and hidden explosives, Greg Buckley Jr. sensed that an attack was imminent. And he knew that it would come from within. The 21-year-old Marine was posted to Garmsir in Helmand Province, where he was training local security forces as part of NATO's planned withdrawal in 2014. It was during a static-filled phone call to his father over the summer that the Long Island native mentioned a run-in he had with an Afghan trainee while on guard duty. NATO releases details of brazen raid on base in Afghanistan . The encounter was the first in which the Buckley family's eldest son seemed to sense something was wrong, according to what he told his family in phone conversations and a letter. "The guy turned around and said to Greg, 'We don't want you here. We don't need you here,'" his dad said. "Greg turned around again and said, 'Why would you say that?'" according to Greg Buckley Sr. But the trainee apparently wouldn't relent, repeating the phrases for hours over the course of a night in which the young Marine was on guard watch. "Greg said, 'I thought I was going to lose my mind,'" his father said. "Pitch black out, and all he kept saying over and over again is, 'We don't want you. We don't need you. We don't want you.'" "It was just tormenting for him." The two men then finally confronted each other, yelling until a group of officers separated them, he told his father. "One of his superiors came over and had Greg apologize to the guy," said the elder Buckley. The 21-year-old agreed and extended his hand, but the man refused. About a month later, Greg phoned his father again. "He told me if I have to stay here until November... I'm not going to come home." Greg also asked his father to prepare to tell his mother and his two younger brothers that he'd be killed. "I don't understand," his father said. "Out in the field?' "No, in our base," Greg replied. 4 NATO troops killed in 'insider' attack in Afghanistan . On August 10, 2012, Greg Buckley Jr. was gunned down by the very forces he had been training, just days after learning that he was to head home early. "It was only two days he had left there in Afghanistan," his father told CNN. The phenomenon is known as "green-on-blue," due to a color-coding system used by NATO. It has become disturbingly more frequent in Afghanistan, with more than 50 NATO troops killed this year by local forces, the first time that's happened in a single year in the U.S.-led war. Last year, 35 people died in such insider attacks, and even less the year before, according to NATO figures. The killings have prompted suspensions of training new recruits while eroding the trust between NATO and its Afghan allies. The gunman involved in Greg's death attacked from inside his outpost and killed two other fellow Marines, his dad said. But Greg Sr. said his son had informed his superior officers that "one day they are going turn around and turn those weapons on us." CNN cannot independently confirm that Greg informed superior officers. Calls and emails to NATO's International Security Assistance Force in Afghanistan were not immediately returned. More than a decade after the war began, the Buckley family is now struggling to cope with the loss of its eldest son. More than 2,000 other U.S. service members have been killed in Operation Enduring Freedom. "It's not really day-by-day," said Greg's mother, Marina Buckley. "It's more minute-by-minute." Back in Oceanside, the Buckley family on Friday attended the town's first home football game, where their fallen son had intended to watch his youngest brother play varsity for the first time. "Greg was supposed to be home for this game," said Justin, 17, who wore the number 30 on his back, Greg's old basketball number. "I would tell him I love him and I miss him." The senior running back, who donned a camouflage jersey along with his team, broke to the outside on Friday for a 25-yard score that helped cement the Sailors' improbable second-half comeback against top-ranked East Meadow. After crossing into the end zone, Justin raised his hand to salute -- honoring his fallen brother. NATO admits killing civilians in Afghan strike .

Example Input: (CNN)At least 10 people and two attackers were killed in Tuesday's attack against the luxurious Corinthia Hotel in Tripoli, Libya, a spokesman for a security division of the Ministry of Interior in Tripoli said. Five foreigners -- one American, one French citizen, and three people from Tajikistan -- were killed in the attack, Essam al-Naas said. Five Libyans were killed. The Libyan branch of ISIS claimed responsibility for the attacks, and released photos of the two gunmen, it said had carried out the attacks as Abu Ibraheem Al-Tunsi and Abu Sulaiman Al-Sudani. Their naming convention indicates that the men were of Tunisian and Sudanese origin, respectively. Al-Naas said it appears the attackers were Libyans. American contractor David Berry was among the people killed in a terrorist attack at the Corinthia Hotel in Tripoli, Libya, on Tuesday, according to Cliff Taylor, chief executive officer of Crucible, a security firm where Berry was working. The FBI is expected to open an investigation into the incident, two U.S. officials told CNN. A State Department official confirmed the death of a U.S. citizen, but would provide no further information. A French citizen was among those killed, according to the French Foreign Ministry. Al-Naas earlier said at least two Libyan security personnel had been killed in the attack and that three gunmen were holed up in the hotel. An online group that supports ISIS said the attack was carried out in the name of Abu Anas al-Libi. Al-Libi was an alleged al Qaeda operative accused of involvement in the bombing of U.S. embassies in Africa. He was captured by U.S. special forces in Libya. He died in a U.S. hospital this month. A spokesman for the Corinthia Group in Malta told CNN there had not been a hostage situation in the hotel, as some reports suggested. "We are trying to take possession of the hotel back to assess the damage," he said, but Libyan security forces were not yet allowing that. The attack began when militants detonated a car bomb in the parking lot of the hotel. The gunmen then shot their way into the hotel. Guests were evacuated to safety, however. The five-star hotel is popular among government officials, some of whom reside there. A witness to the events told CNN that all roads leading to the Corinthia Hotel had been sealed by security forces. People were warned to stay away, the witness said, adding that there had been exchanges of gunfire. CNN's Mohammed Tawfeeq and Stephanie Halasz contributed to this report.

Example Input: (CNN) -- The hostage crisis in eastern Algeria is over, but the questions remain. Among them, exactly how many people are unaccounted for at a remote natural gas facility after three days of chaos that ended Saturday, leaving at least 23 hostages and dozens of Islamist militants dead. Some 685 Algerian workers and 107 foreigners were freed, the Algerian Interior Ministry said. Britain's BP said Sunday four of its workers remain unaccounted for. And Norway's Statoil said five of its employees were missing, while 12 others are now home in Norway, Algeria and Canada. "Search efforts are ongoing at the gas installation, looking for more possible victims. I fear the numbers will be updated with more victims later today when the search operation is expected to end," said Mohammed Said, Algeria's communication minister. The attackers came from six countries -- only three were Algerian -- and included Arabs and Africans, Said told state-run Radio Algeria. Algeria's military found numerous "foreign military uniforms" in its sweep of the In Amenas facility, its Interior Ministry said. Mauritania's Sahara Media news agency said Sunday it had a video from Moktar Belmoktar, who leads the Al-Mulathameen Brigade associated with al Qaeda in the Islamic Maghreb that regional media have reported was behind the attack. In it, Belmoktar said, "We at al Qaeda are claiming responsibility of this blessed guerrilla operation." Belmoktar has communicated with this and other news sites before, said Andrew Lebovich, a Senegal-based security analyst. But the news agency did not post the video, and CNN has not independently confirmed its authenticity. Eleven former hostages -- among them British citizens -- have gotten medical treatment and psychological counseling from the U.S. military at a U.S. naval base in Sigonella, Italy, a U.S. official said Sunday. The hostages were brought from Algeria to the base Friday, the official said, and are being flown to their home countries as their conditions warrant. The remains of one American hostage were also brought to the base, the official said. In a statement Saturday night, the White House said it was in close contact with Algeria's government to "gain a fuller understanding of what took place." British Foreign Secretary William Hague echoed those remarks, adding his government is "working hard to get definitive information" about each individual. Japan has 10 citizens -- likely affiliated with JGC Corp., an engineering firm that was involved in gas production in In Amenas -- who are yet to be confirmed safe, in addition to a number of dead. Opinion: Algeria crisis is a wakeup call for America . Such Islamist militant activity is not new to Africa, including recent violence in Mali and Somalia. Algeria's status as Africa's largest natural gas producer and a major supplier of the product to Europe heightens its importance to those who want to invest there. Yet that interest is coupled with pressure to make sure foreign nationals, and their business ventures, are safe. Youcef Yousfi, Algeria's energy and mining minister, insisted Sunday his country can keep its gas facilities secure and ruled out foreign forces coming in to help. "We are going to strengthen security, and we rely first on our means and resources," Yousfi said, according to the official Algerian Press Service. Raids turn deadly . Militants in pickup trucks struck the sprawling gas complex about 50 kilometers (30 miles) west of the Libyan border at dawn Wednesday, gathered the Westerners who worked there into a group and tied them up. The In Amenas plant is run by Algeria's state oil company, in cooperation with foreign firms such as Statoil and BP, and because of that employed workers from several countries. The kidnappers wielded AK-47 rifles and put explosive-laden vests on some hostages, according to a U.S. State Department official. Algeria said the attack was in retaliation for allowing France to use Algerian airspace for an offensive against Islamist militants in neighboring Mali. And Sahara News' report Sunday claimed Belmoktar said "40 immigrant Jihadists and supporters of Muslim countries" led the siege in retaliation for the Mali offensive.

On Thursday, Algerian special forces moved in because the government said the militants wanted to flee to Mali. The Islamic extremists also planned to blow up the gas installation and rigged it with mines throughout, the U.S. official said. Thursday's military incursion succeeded in freeing some hostages -- but not all. Some survivors described their harrowing escapes by rigging up disguises and sneaking to safety with locals, with at least one survivor running for his life with plastic explosives strapped around his neck. Several hostages died. And the Algerian military came under criticism from some quarters for unnecessarily endangering hostages' lives. Undeterred, the government followed with a second push Saturday. That assault killed the remaining hostage-takers but resulted in more hostage deaths. The army intervened "to avoid a bloody turning point of events in this extremely dangerous situation," the Algerian Interior Ministry said Saturday. "It was clear that the terrorists were determined to escape the country with the captives and to bomb the gas installations." On Sunday, an American lawmaker said the Algerian government turned down U.S. offers to help during the crisis. "They decided they were going to handle it their way," said Rep. Mike Rogers, a Michigan Republican who is chairman of the U.S. House Intelligence Committee. "They did not want us or the other hostage nations involved in the decision-making." British Defense Secretary Philip Hammond called the loss of life "appalling and unacceptable," while laying blame solely on the terrorists. Countries mourn dead, try to track down missing . While the military part of the operation is over, the searching and mourning is not for people in countries worldwide. In addition to combing the sprawling desert site, Algerian forces are searching hospitals and medical centers around the country, as well as towns and villages near the targeted site, according to a statement Sunday from Statoil.

No known French hostages are unaccounted for, France's Defense Ministry said Saturday. One man -- identified as Yann Desjeux -- died after telling the French newspaper Sud Ouest on Thursday that he and 34 other hostages of nine different nationalities were treated well. Three others who had been held are safe. Japan . There are still 10 Japanese who have yet to be confirmed safe, JGC -- the engineering firm -- said Sunday. Malaysia . Three hostages were on their way back to Malaysia, the country's state-run news agency reported Sunday. But there is a "worrying possibility" that another is dead, while a fifth is unaccounted for, the agency said. Norway . Five Norwegians are missing, while eight are safe, Norwegian Prime Minister Jens Stoltenberg said. "We know that there are many fatalities," Statoil CEO Helge Lund said Sunday. "A new day without answers has increased our concern." Romania . One Romanian lost his life, the country's Foreign Ministry said Saturday. Four other Romanians were freed. United Kingdom . Three British citizens were killed, the Foreign Office said Sunday. Three other British nationals and a UK resident are also "believed dead," he said. Twenty-two other Britons who were taken hostage have safely returned home. United States . At least one American, identified as Frederick Buttaccio, is among the dead, the State Department said. Six freed Americans left Algeria and one remained. Read more: Algeria attack may have link to Libya camps .
