Daesh's affiliate in Egypt has claimed responsibility for the Russian plane crash in the Sinai Peninsula, AFP reported.
According to a statement released on social media, "the soldiers of the caliphate succeeded in bringing down a Russian plane in Sinai."
However, these reports contradict the findings of a preliminary investigation of the crash site that indicated a technical fault caused the crash. Russian Transport Minister Maxim Sokolov dismissed the militants' claim, saying it "cannot be seen as credible."
The plane's altitude also makes Daesh's statement suspect. As TIME reports, the carrier was flying at around 30,000 feet when it disappeared from the radar Saturday morning, a distance far beyond the reach of the militant group's surface-to-air missiles.
The passenger plane was heading to St. Petersburg, Russia before crashing vertically in a mountainous area of central Sinai, killing all 224 passengers and employees on board.
