For the first time in almost a week, international experts have been able to visit the scene of the MH17 crash.
Access to site had been restricted due to fighting between Ukrainian forces and pro-Russian rebels.
Police and forensic experts from the Netherlands and Australia are expected to initially focus their efforts on retrieving bodies still at the site and collecting victims' belongings.
The Organisation for Security and Cooperation in Europe's monitoring mission tweeted:

The Malaysia Airlines flight crashed over Ukraine while flying from Amsterdam to Kuala Lumpur on July 17th.
Earlier this week, a Ukrainian security official claimed black box data from the downed Malaysia Airlines plane revealed the jet crashed due to a "massive explosive decompression" after being hit by shrapnel from a missile.
Andriy Lysenko, a spokesman for Ukraine's Security Council, said the information came from experts analysing the flight recorders from MH17, which was shot down over eastern Ukraine killing all 298 people on board.
