Shortly after the crash, the Islamic State of Iraq and the Levant (ISIL)'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.
