Ukraine has accused pro-Russian militiamen at the site of the Malaysia Airlines crash of trying to destroy evidence of an “international crime”.
For a second day, OSCE monitors at the scene have had their movements restricted by militiamen.
Reports that bodies have been moved prompted anger from the Netherlands. Most of passengers were Dutch.
The jet was reportedly hit by a missile over a rebel-held area in east Ukraine on Thursday. All 298 people died.
Both Ukraine and the rebels have accused each other of shooting it down.
The Boeing 777 flight MH17 was flying from Amsterdam to Kuala Lumpur. It fell between Krasni Luch in Luhansk region and Shakhtarsk in the neighbouring region of Donetsk.
The passenger list released by Malaysia Airlines shows the plane was carrying 193 Dutch nationals (including one with dual US nationality), 43 Malaysians (including 15 crew), 27 Australians, 12 Indonesians and 10 Britons (including one with dual South African nationality), four Germans, four Belgians, three from the Philippines, and one each from Canada and New Zealand.
