Human remains found at the crash site of EgyptAir flight MS804 point to an explosion on board the plane, an Egyptian official has told the Associated Press.
The official is part of the Egyptian investigative team and has personally examined the remains in Cairo.
He said all 80 pieces brought to Cairo so far are small and that "there isn't even a whole body part, like an arm or a head".
The official added that "the logical explanation is that it was an explosion".
There has so far been no confirmed cause of the crash.
An Egyptian official said on Monday that flight MS804 'did not swerve' before plunging and crashing, contradicting earlier reports.
The plane was on its way from Paris to Cairo when it disappeared from radar.
It went missing with 66 people on board and search teams have since found debris from the flight in the Mediterranean Sea.
