ISIS has publicly executed a Syrian it accused of planting tracking devices for deadly regime airstrikes, SITE Intelligence reported Saturday.

The jihadist group posted footage of the accused being paraded before a crowd but the video deliberately freezes at the point an ISIS fighter pulls his head back and holds a knife to his neck, the U.S.-based monitoring group said.

After the execution in Syria's northern province of Aleppo, the jihadists paraded the body of the accused on a cross.

ISIS charged that more than 190 people had been killed in the air strikes that the man had abetted.
