Human Remains, Plane Seat, Luggage Found Near Where EgyptAir Flight Disappeared, Greek Officials Say

WATCH: Debris From EgyptAir Plane Found, Egyptian Officials Say

Human remains, an airplane seat and luggage were found about 5 miles south of where an EgyptAir flight lost contact with radar and went missing over the Mediterranean Sea, a Greek official said today.

Wreckage and passenger belongings were spotted about 180 miles north off the coast of the Mediterranean port city of Alexandria, Egyptian officials said, and an airline official said later today that Egyptian military and marine forces discovered more debris, passengers’ belongings, body parts, luggage and aircraft seats, but the search is still in progress.

A "potential oil slick" from the plane was also spotted by a satellite in the area where the aircraft went missing, the European Space Agency said today.

The missing plane was en route to Cairo from Paris when it disappeared early Thursday with 66 aboard. The plane lost contact with the radar tracking system at 2:45 a.m. at an altitude of 37,000 feet, according to EgyptAir.

Egyptian officials said earlier the incident was more likely caused by terrorism than a technical problem.

"I don’t want to go to assumptions like others, but if you analyze the situation properly, the possibility...of having a terror attack is higher than having a technical [failure,]" Egyptian aviation minister Sherif Fathi told reporters Thursday.

U.S. officials said its government satellites have shown no indications of an explosion along the flight path.

But the Egyptian military says no distress call was received from the pilot.
