The Egyptian military regime Saturday released photos of debris north of Alexandria from missing EgyptAir Flight 804, which disappeared Thursday. So far the images provide glimpses of clues but no concrete answers to what happened to the Airbus carrying 66 people this week.

A spokesperson for the Egyptian military posted the photos on Facebook. They show ragged fragments of plane seats, life vests and luggage. Investigators also found body parts amid the debris, the BBC reported.

Midway through a flight from Paris to Cairo, the plane swerved 90 degrees to the left, made a 360-degree turn to the right, then dove to 10,000 feet and disappeared from radar screens altogether, CNN reported.

Thirty of the passengers were Egyptian, in addition to 15 French citizens and a remaining share of nationals from across the world.

While the sequence of events has come together, the broader story remains foggy: The Aviation Herald reported before the plane’s signal went out, smoke detectors had activated in the bathrooms. 

The Egyptian military has already settled on terrorism as the cause. However, French Foreign Minister Jean-Marc Ayrault said all theories “are being examined, and none is favored,” the BBC reported.
