An Australian Special Air Service Regiment (SASR) operator and the most decorated Australian soldier alive has sued three newspapers for defamation over war crimes allegations.

Corporal Ben Roberts-Smith is suing The Sydney Morning Herald, The Canberra Times and The Age for accusing him of war crimes.

The Australian Federal Police (AFP) is investigating Cpl. Roberts-Smith and other special operators about potential war crimes perpetrated in Afghanistan. This is the second ongoing investigation on the decorated SAS operator for illegal actions during his Afghanistan deployments.

More specifically, the SAS operator is suspected of taking a handcuffed Afghan to the edge of a small cliff and kicking him off during an operation on September 12, 2012, in the village of Darwan. Then, he allegedly ordered a junior SAS operator to shoot the injured prisoner.
