Australia said on Thursday that 19 current and former soldiers will be referred for potential criminal prosecution for allegedly killing 39 Afghan locals, the majority of whom had been captured and unarmed.

Detailing the findings of the long-awaited inquiry into the conduct of special forces personnel in Afghanistan between 2005 and 2016, Australia's Gen. Angus John Campbell said there was credible information of 39 unlawful killings by 25 Australian Special Forces personnel in 23 separate incidents.

All of those kills were outside the "heat of battle," Campbell said.
