PARIS (AP) The French agency investigating last week's crash of a Yemenia Airways flight to the Comoros says a submarine taking part in the search has picked up signals from the aircraft's two black boxes.

The accident investigating agency BEA said the signals were picked up on Sunday morning during a submarine search for the black boxes, which are critical to understanding the cause of Tuesday's crash off the Comoros Coast.

A 12-year-old girl is the only survivor of the crash that killed 152 people on the flight from Paris to Moroni, the capital of the Comoros.

BEA's one-line statement gave no indication of when the flight data record and the cockpit voice recorder in the black boxes might be recovered.
