    BEIJING, June 23 (Xinhuanet) -- Signals detected by the French navy were not coming from the black boxes of the crashed Air France Flight 447, a French official said Tuesday, ruling out earlier reports of the jetliner's sounds in the French media.

    Earlier, the French publication Le Monde reported that beacon signals emitted by the black boxes frequently from the day of the crash on June 1 were picked up by French ships and the mini submarine Nautile has been launched to investigate the signal.

    The aide to France's top transport official, Jean-Louis Borloo, told The Associated Press that the "black boxes have not been detected."

    She spoke on the condition of anonymity.

    The aide confirmed that French military ships searching in the area where the plane crashed have "heard sounds" but that those were not signals from the flight's voice or data recorders.
