Daesh militants burned four Iraqi Shia fighters alive in new footage posted online, according to AFP.

The gruesome footage showed the four men believed to be members of the pro-government Popular Mobilization forces, strung up in chains before being set alight.

“Now retribution has come, for today, we will attack them as they attacked us, and punish them as they punished us,” a masked Daesh militant said in the video, AFP reports.

Daesh continues to release propaganda videos of mass executions across Syria and Iraq since it launched its so-called “Caliphate” in Mosul last year.
