France has said that it will begin a third search for the black boxes of its Airbus A330 that crashed off the coast of Brazil in June this year, killing all 228 passengers on board.

The announcement was made after a meeting with the relatives of the deceased.

The cause of the crash is still unknown; an extensive search of the Atlantic is due from February next year.

Experts from the US Navy and National Transportation Safety Board, along with private contractors, will assist in the investigations and search of the cockpit audio and data recorders.
