On Tuesday, a senior Egyptian forensics official said that human remains salvaged from the wreckage of EgyptAir Flight 804 suggest there was an explosion on board before the plane went down in the Mediterranean last week. So far, 80 remnants of the 66 people aboard the flight have been brought to the Cairo morgue, and "there isn't even a whole body part, like an arm or a head," the unidentified official told The Associated Press.
