KIEV, July 23 - Two black boxes taken from the crash site of Malaysia Airlines flight MH17 have arrived in Britain for analysis, Ukraine's government investigation commission said Wednesday.

The flight data recorders have been sent to a laboratory in Farnborough in southern England under the supervision of experts from the International Civil Aviation Organization (ICAO), the commission said in a statement.

According to the statement, Ukraine did not extract the information from the black boxes before handing over them to international experts.

MH17, a Boeing 777 en route from Amsterdam to Kuala Lumpur, crashed near the eastern Ukrainian city of Donetsk Thursday, killing all 298 people on board.

On Tuesday, insurgents in eastern Ukraine handed over to Malaysian experts the black boxes of the ill-fated plane, which was allegedly shot down by a missle in the rebel-held Donetsk region.
