An agreement has been reached with separatists in Ukraine to enable international police to oversee a site where a Malaysian plane was downed and investigators to determine why the aircraft crashed, Malaysia's prime minister said on Sunday.
Pro-Russian separatists remain in control of the site where Malaysia Airlines flight MH17 was shot down earlier this month and have restricted access to rescue teams and investigators.
Eastern regions are gripped by heavy fighting as Ukrainian government forces try to dislodge the separatists.
A statement issued by Prime Minister Najib Razak's office said the agreement with separatist leader Aleksander Borodai would "provide protection for international crash investigators" to recover human remains and ascertain the cause of the crash.

Among the 298 people who died aboard the Boeing 777 on its flight from Amsterdam to Kuala Lumpur on July 17 were 193 Dutch nationals, 43 Malaysians and 28 Australians.
Najib on Saturday said the separatists had fulfilled two of three conditions of a earlier deal struck - the return of victims' bodies and of the plane's two "black boxes" - and it was now time to proceed with the investigation.
Malaysian experts have said they believe at least 30 investigators will be required to cover the full site of the crash, in addition to Dutch investigators and an expert from the United Nations' civil aviation body, the ICAO.
The United States and other Western countries suggest the separatists downed the plane with a surface-to-air missile supplied by Russia. The separatists deny shooting down the plane and Russia says it has provided no such weapons.
POLICE TO MOVE IN
In the Australian capital Canberra, Prime Minister Tony Abbott said an unarmed police mission led by the Netherlands and made up of about 49 officers would travel to the site. Officials said a total of 170 Australian police were deployed in Ukraine.
