Metrojet Flight 9268 was an international chartered passenger flight, operated by Russian airline Kogalymavia (branded as Metrojet). On 31 October 2015, at 06:13 local time EST (04:13 UTC), an Airbus A321-231 operating the flight was destroyed by a bomb above the northern Sinai Peninsula following its departure from Sharm El Sheikh International Airport, Egypt en route to Pulkovo Airport, Saint Petersburg, Russia. All 224 passengers and crew on board were killed. The cause of the crash was most likely an onboard explosive device as concluded by Russian investigators.Most of the people aboard the flight were tourists. There were 212 Russians, four Ukrainians, and one Belarusian passenger. There were also 7 crew members on board. Investigators believe that a bomb was put on the aircraft at Sharm El Sheikh, with the goal of causing airlines to suspend flights to that airport.Shortly after the crash, the Islamic State's Sinai Branch, previously known as Ansar Bait al-Maqdis, claimed responsibility for the incident, which occurred in the vicinity of the Sinai insurgency. ISIL claimed responsibility on Twitter, on video, and in a statement by Abu Osama al-Masri, the leader of the group's Sinai branch. ISIL posted pictures of what it said was the bomb in Dabiq, its online magazine.By 4 November 2015, British and American authorities suspected that a bomb was responsible for the crash. On 8 November 2015, an anonymous member of the Egyptian investigation team said the investigators were "90 percent sure" that the jet was brought down by a bomb. Lead investigator Ayman al-Muqaddam said that other possible causes of the crash included a fuel explosion, metal fatigue, and lithium batteries overheating. The Russian Federal Security Service announced on 17 November 2015 that they were sure that it was a terrorist attack, caused by an improvised bomb containing the equivalent of up to 1 kilogram (2.2 lb) of TNT that detonated during the flight. The Russians said they had found explosive residue as evidence. On 24 February 2016, Egyptian President Abdel Fattah el-Sisi acknowledged that terrorism caused the crash.In March 2020, an Egyptian appeals court ruled the crash was not an act of terrorism, and it dismissed lawsuits against government officials, Metrojet and Ingosstrakh. The appeals court ruled that the identities of the 224 victims had not been officially established and it was impossible to issue compensation to them as a result.
