MH17: Crash of the plane was due to 'massive explosive decompression' - investigators

Black boxes recovered from downed Malaysia Airlines flight MH17 in rebel-held east Ukraine show shrapnel from a rocket explosion caused the passenger jet to crash, a Ukrainian security official said Monday.

International investigators "indicated that data from flight recorders show that the reason for the destruction and crash of the plane was massive explosive decompression arising from multiple shrapnel perforations from a rocket explosion," Andriy Lysenko, spokesman for Ukraine's National Security and Defence Council, said.

Data from the doomed airliner's black boxes was decrypted in Britain after being handed over to Malaysian officials by pro-Russian rebels controlling the crash site of MH17.

Investigators leading the probe in the Netherlands -- which lost 193 citizens on the doomed jet -- refused to confirm the latest information from Kiev, saying that they were "waiting to get a more complete idea of what happened."

Kiev and its Western allies have accused insurgents of shooting down the plane, killing all 298 people on board.
