The Islamic State released a video on Monday showing four hogtied Iraqi men being strung up and burned alive.

The latest in a long line of gruesome execution videos by the jihadis created yet another negative international sensation.

The terrorists accused the men of being part of a Shiite militia. They were suspended from a swing-set by chains attached to their hands and feet, and then set on fire with a torch and a flammable liquid.

A masked IS gunman, speaking in Arabic, said the executions were in revenge for the alleged torching of four Sunnis by pro-government forces.

“Now retribution has come, for today, we will attack them as they attacked us, and punish them as they punished us,” a masked militant says in the video, which was not dated and did not say where the gruesome act took place.
