Islamic cavemen doing what Islamic cavemen do best, killing people in the most gruesome ways imaginable.

(Reuters) – Islamic State’s self-declared police force in western Syria decapitated four men after accusing them of blasphemy, a rights group monitoring the Syrian conflict said on Saturday.

The men were beheaded in the countryside east of the city of Homs by the militant group’s “Islamic Police”, the British-based Syrian Observatory for Human Rights said.

The Observatory also reported on Saturday that Islamic State had stoned a man and a woman to death for adultery in Manbij town in northern Syria after Friday prayers.
