US Ambassador to the UN, Samantha Power, has told a UN Security Council meeting that the US cannot rule out help from Russia in the launch of the surface-to-air missile that shot down a Malaysian airlines jet, killing all 298 people on board.
International investigators have arrived at the crash site of Malaysia Airlines flight MH17, after rebels in eastern Ukraine allowed them access.
The plane crashed in rebel-held territory on Thursday.
