European monitors in Ukraine say pieces of the wreckage at the crash site of the Malaysia Airlines plane have been cut into, which could compromise any investigation into the tragedy.
The search for answers to the crash is expected to lie in a forensic examination of parts of the plane as it could determine what type of missile was used to bring it down, and who fired it.
Flight MH17 crashed in an area held by pro-Russia rebels on 17 July, killing all 298 people on board. It was shot down by what is believed to be a surface-to-air missile.
Organisation for Security and Co-operation in Europe (OSCE) spokesperson Michael Bociurkiw said large parts of the wreckage looked different to a few days ago.
