Almost a month after an EgyptAir flight from Paris to Cairo went missing with 66 people on board, officials say that several main sections of the plane have been discovered at the bottom of the Mediterranean Sea, UPI reports.

Although investigators are still piecing together the sequence of events that led to the sudden disappearance of EgyptAir Flight 804 last Wednesday night, officials from several nations are in agreement on one key fact: It was probably terrorists.

EgyptAir has confirmed that Flight MS804, carrying at least 56 passengers and 10 crew members from Paris to Cairo, has disappeared.
