Lebanese authorities say a black box recovered from the wreckage of the Ethiopian Airlines jet that crashed into the Mediterranean last month has been flown to France for analysis.

The Boeing 737 crashed Jan. 25 minutes after takeoff from Beirut, killing all 90 people on board.

An official at Beirut airport said a private jet owned by the Lebanese prime minister left for Paris Monday carrying the flight data recorder. The official spoke on condition of anonymity because he was not authorized to speak to the media.

Lebanese authorities have said the black box will be analyzed by BEA, a French agency that specializes in assisting with technical investigations of air crashes. The plane's other black box, the cockpit flight recorder, has not been recovered.
