ISIS executes Syrian for aiding regime air strikes: Monitoring group

BEIRUT (AFP) - The Islamic State in Iraq and Syria (ISIS) has publicly executed a Syrian it accused of planting tracking devices for deadly regime air strikes, SITE Intelligence reported on Saturday.

The militant 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 United States-based monitoring group said.

After the execution in Syria's northern province of Aleppo, the militants 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. In October and November, the Syrian regime sharply intensified its air strikes on areas held by ISIS or other rebel groups. In just 40 days, some 2,000 strikes killed more than 500 people, the Syrian Observatory for Human Rights said.

Some of the deadliest hit the ISIS "capital" of Raqqa on Nov 25, killing at least 95 people, but air strikes have also hit the militants in the eastern part of Aleppo province which they control.

ISIS has earned worldwide notoriety for its release of often grisly video footage of its executions of Western hostages, captured soldiers and civilians accused of breaching its brutal version of Islamic law.
