According to Egyptian officials, a Russian airliner crashed early Saturday in Egypt’s Sinai Peninsula, killing all 224 people aboard. The Airbus A321 was owned and operated by Kogalymaviabetter known as MetroJet.

Egyptian officials do not suspect foul play, despite claims by ISIS that it is responsible for the downing of the airliner. The terrorist group has even released a video allegedly showing the ill-fated jet as it explodes and goes down. There was nothing out of the ordinary reported on a preflight inspection, according to Egyptian Civil Aviation Minister Hossam Kamel.

Russian media outlets are reporting many of the 217 passengers aboard Flight 9268, which departed Sharm el-Sheikh near the southern tip of the Sinai Peninsula on the Red Sea side, were returning home from vacation. It disappeared from air traffic control radar displays at approximately 0620 a.m.—23 minutes into the flight.
