Pro-Russian separatists have been accused of removing 38 bodies from the Malaysia Airlines crash scene and attempting to destroy evidence at the site.
Ukraine emergency officials remove a body from the crash scene The Ukraine government said "terrorists, with the help of Russia, are trying to destroy evidence of international crimes", adding it had obtained data which showed bodies had been taken to a morgue in Donetsk.
However, Sky's Chief Correspondent Stuart Ramsay, at the scene, said there were reports rebels had moved bodies on Friday, but body parts were now officially being removed by Ukraine emergency ministry staff.
Ukraine's Security Council said 18sq km of the 25sq km had been explored and 186 bodies found.

The fresh claims came amid discussions between the two factions over the creation of a "security zone" around the crash scene following allegations of looting and evidence being compromised, without a deal being reached.
Concerns have been raised by Malaysia about the investigation into the disaster as a team of international observers complained of being confronted by aggressive armed rebels, blocking their access to the crash site for a second consecutive day.
Ramsay said: "I know in the past shots have been fired as warnings."
Security monitors speak to a separatist at the crash scene Critically, the monitors have been unable to speak to anyone about the whereabouts of the jet's two black box voice and data recorders.
Ukraine said they had not been handed over to Kiev and it had no information about them.
Alexander Borodai, head of the self-proclaimed Donetsk People's Republic, denied rebels had shot down the plane, or found the black boxes, or removed bodies. But he said body parts which had fallen into people's properties had been taken away.
Russia's foreign ministry urged rebels to grant monitors access to the site, while Malaysia's transport minister Liow Tiong Lai on Saturday attacked the failure to preserve evidence a "betrayal of the lives lost"
The debris was scattered over a wide area Reports of looting and valuables such as credit cards and cash being taken from victims' bodies and luggage were "gaining currency", said Sky's Michelle Clifford, in Donetsk.
"It may be part of a narrative to discredit the rebels," she said. "But, I have just spoken to a contact I trust and he said with his own eyes he saw the rebels taking money and valuables from luggage at the site."
Some 298 people, including 10 Britons and 80 children were killed when flight MH17, flying from Amsterdam to Kuala Lumpur, was brought down near Grabovo, Donetsk, where Ukrainian forces have been battling separatists.
Ukraine and Russia have blamed each other for the disaster.
A children's toy lies among the passengers' possessions Hugh Dunleavy, Malaysia Airlines's commercial director, defended the aircraft's flightpath and told Sky News up until now there had been no incident involving a civilian plane flying over the war zone.
Reports suggested pro-Russian separatist commander Igor Strelkov had made bizarre claims bodies at the crash site had been there for days.
However, postings on his VK.com account, Russia's version of Facebook, showed he actually questioned this: "Version with a plane full of corpses, exciting, of course, but somehow can not (sic) see sense."
