Pro-Russian rebels have handed over two flight-data recorders from the downed MH17 plane to Malaysian experts.
The handover came hours after the UN Security Council voted unanimously to demand immediate international access to the crash site, reports the BBC.
Experts say the "black boxes" will reveal the exact time of the incident and the altitude and precise position of the aircraft.
They should also contain the cockpit voice recorder, which it is hoped will provide clues as to what the cause of the crash was.
