Australian commando under investigation over 2012 Afghanistan rotation | 7.30

7.30 has new accounts of a deadly raid carried out in Helmand province in 2012. Multiple witnesses have told 7.30 that seven Afghans were killed, some allegedly shot after they were detained by a small group of Australian soldiers. We'll hear an account of a commando's remorse at his alleged actions in that operation. The allegations are now part of a probe by Australia's specialist war crimes investigations office. Mark Willacy from ABC Investigations and producer Alex McDonald have this exclusive report which contains strong language, images of war and descriptions of killings. Editor's note: In his final comment in this story former DEA team leader Bret Hamilton says that alleged war crimes should be investigated. Mr Hamilton was referring to war crimes in general. He was not referring to any specific allegations about 2nd Commando Regiment and that was not the meaning we intended to convey. The ABC sincerely apologises to Mr Hamilton. We sincerely regret if any audience members were misled.
