It has been reported that the black boxes from MH17 have been handed over to the Malaysian experts. This happened in the city of Donetsk. The handover happened hours after international pressure for access to the crash site from the UN Security Council.
The Malaysian Airlines passenger jet crashed last Thursday, killing all 298 people on board.
There is growing evidence that flight MH17 was hit by a Russian-supplied missile fired by rebels.
The black boxes are reported to be in good condition and should help in the investigation. They can provide the exact time of the impact of a possible missile.
A Ukrainian train carrying bodies from the Malaysia Airlines plane crash has left the station of the town of Torez.
Earlier in the day Pro-Russian separatists, who are in control of the crash site, allowed Dutch investigators to examine the bodies of the passengers refrigerated in the train's carriages.
Four days after flight MH17 crashed, the US and other nations say there is growing evidence of Russian complicity in the crash.
