"I can’t verify the authenticity of the video, which has been released on the one-year anniversary of the disaster. It is sickening to watch and, 12 months on from the downing of MH17, it is deeply concerning that this footage has emerged now," she said, according to The Sydney Morning Herald.

"It is revolting to watch," Bishop said.

"Their grief is inconsolable and the burden of grieving and then seeing this footage will be almost too much to bear."

Bishop also flagged a second investigation report into the tragedy is expected to be released in October.

The next step is to establish an international criminal tribunal, but Bishop acknowledged it would be tough to get it approved by the United Nations Security Council.

As UNIAN reported earlier, journalists of News Corp Australia published footage shot by militants from the crash scene right after the tragedy.
