Debris from the Egyptair flight 804, which crashed in the Mediterranean with 66 people on board on Thursday, has been found by the Egyptian military forces.

The passenger belongings and aircraft parts were found 180 miles north of Alexandria, the military says. The plane swerved sharply then plunged from 37,000 feet to 10,000 feet after entering Cairo airspace, the Greek officials say.  The cause of the crash is believed to be most likely terrorism rather than technical fault.

Egypt said on Friday that its navy had found human remains, wreckage and the personal belongings of passengers floating in the Mediterranean, verification that an EgyptAir jet had plunged into the sea with 66 people on board. President Abdel Fattah al-Sisi offered commiserations for those on board, amounting to Egypt’s official acknowledgement of their deaths, although there was still no explanation of why the Airbus had crashed.
