New video footage emerges of aftermath of MH17 crash

New video footage has emerged showing Russian-backed rebels arriving at the scene of the MH17 crash in eastern Ukraine, believing they'd shot down a Ukrainian fighter jet.

The footage - which was reportedly filmed by the rebels themselves and released exclusively by News Corp Australia - allegedly shows the insurgents dismay as they discover the aircraft is a commercial airliner.

It also shows the rebels rifling through the luggage of passengers and crew.
