From the London Daily Mail:
Now ISIS is under attack from guerrillas itself: Ultra-secret White Shroud group strike fear into terrorists by picking off
fighters one by one
Terrorist organisation Islamic State is now under attack from guerrillas itself, it was revealed today,
Small groups of Syrians are hunting down ISIS fighters in one of their main strongholds in eastern Syria in a new guerrilla campaign that has emerged as a response to the Islamists' growing brutality.
The main aim is to generate fear in ISIS’s ranks, said the head of ‘White Shroud’ - a group that says it has killed more than 100 of the militants' fighters in attacks in Deir al-Zor province in recent months.
Could not be happening to a more deserving bunch of people...
