Malaysian Prime Minister Najib Razak says the leader of the pro-Russian rebels has agreed to hand over both black boxes from Flight 17 to Malaysian investigators who are in Ukraine.
Najib also said that the remains of 282 of the crash victims currently in Torez are being moved by train to Kharkiv in Ukraine, where they will be handed over to Dutch authorities. The remains will then be flown to Amsterdam.
Najib also said that as part of an agreement he reached with rebel leader Alexander Borodai Monday night, independent international investigators will be given "safe access" to the crash site.
This comes just after President Barack Obama called for international investigators to have "immediate and full access" to the site in eastern Ukraine, where a passenger jet was shot down last week.
President Obama accused pro-Russian separatists in the area of removing evidence and bodies from the crash site. He says that raising the question of "what exactly are they trying to hide?"
The president says the burden is on Russia and President Vladimir Putin to compel the separatists to cooperate with the investigation. President Obama says that if Russia continues to violate Ukraine's sovereignty, Moscow "will only further isolate itself" and the economic costs will continue to increase.
The White House says the missile that brought down the Malaysia Airlines plane was fired from an area controlled by the separatists.
Earlier Monday, a refrigerated train bearing the bodies of many of the 298 people killed in the Malaysia Airlines plane disaster pulled away from a rebel-held town in eastern Ukraine.
An AP reporter saw the train leave from the town of Torez,15 kilometers (9 miles) from the crash site itself.
