A Ukrainian security spokesman says data from the recovered flight data recorders shows Malaysia Airlines Flight MH17 crashed due to a massive, explosive loss of pressure after being punctured multiple times by shrapnel.
National security spokesman Andriy Lysenko said Monday that the plane suffered "massive explosive decompression" after it was hit by fragments he said came from a missile.
The data recorders were sent to experts in Britain for examination.
Flight MH17 went down on July 17 as it flew from Amsterdam toward Kuala Lumpur. All 298 people aboard died. The U.S. and Ukrainian governments say it was shot down by a missile fired from territory held by armed pro-Russian separatists, probably by mistake.
The separatists deny shooting down the plane; Russia says the Ukrainian military may have shot it down.
