Brother executes brother in gruesome ISIS video

ERBIL, Kurdistan Region - In a new shocking execution video released by the Islamic State, a militant shot dead his own brother on charges of spying for the Iraqi army, Kurdish Peshmerga forces, and the US-led coalition.

The footage shows an executioner, identified as Abu Abdullah, saying a prayer before he gunned down his older brother. Another blindfolded militant was killed by a second executioner on the same charge.

The footage, reportedly filmed in Iraq, opened with two militants wearing balaclavas bringing in the two blindfolded men, one of whom was identified as Abu Abdullah's brother.

The executioner then sent out a threatening message to those trying to leak intelligence information to the Iraqi and other counter-ISIS forces.

He also warned his family not to get involved in the matter of him killing his older brother.

The video was released as the group has been suffering a string of military defeats on multiple battlefields in Fallujah and surrounding Mosul in Iraq, and Manbij in Syria.

The grisly killing comes five months after another Islamic State fighter killed his mother after she had reportedly tried to escape the group in Syria.
