Officials are still trying to figure out what caused EgyptAir Flight 804 to crash. But more and more evidence appears to be pointing to an explosion onboard.
Reports surfaced Tuesday claiming that body parts recovered from the downed flight "confirm" an explosion took place.
"Investigators are working on [the body parts] right now. They are inspecting these parts. We understand they are really, really small parts, and it might take up to two weeks before, or even more, until the DNA tests are finished and results are announced," a BBC reporter said.
Officials have yet to rule out a mechanical failure or terrorism, although it's important to note no terrorist group has claimed responsibility for the crash.
Over the weekend, a BEA official — the French government agency that investigates aviation crashes — said the plane's smoke alarms went off shortly before it went down. Still, officials haven't determined why.
Egyptian officials say the plane didn't swerve before disappearing from radar, although officials in Greece say the plane turned 90 degrees to the left and then 360 degrees to the right before going down.
The plane was flying from Paris to Cairo last week when it crashed into the Mediterranean Sea. All 56 passengers and 10 crew members onboard were killed.
