Investigators find parts of downed Air France jet

French investigators said Sunday that they have found pieces of the Air France jet that crashed in the Atlantic Ocean in 2009, killing all 228 people on board.

Air France Flight 447 disappeared after taking off from Rio de Janeiro on its way to Paris.

France's air accident investigation agency, the BEA, said that a team -- led by the Woods Hole Oceanographic Institution -- discovered parts of the aircraft during an underwater search operation conducted within the past 24 hours.

The agency did not immediately say what parts of the jet the team found.

Investigators have not yet established what caused the crash, and large parts of the plane -- including both flight recorders -- have never been located, despite an extensive search operation that included a French navy submarine.
