The Islamic State militants executed at least five men in Syria on charges of spying for the Syrian regime, a monitoring group said on Saturday. 

Isis carried out the mass executions in a desert region in Homs, the Syrian Observatory for Human Rights said on its website, stating that it had received footage of the killings. 

The footage reportedly shows five blindfolded prisoners in orange jumpsuits being dragged to the desert and then lined up for execution.

Five Isis militants holding machine guns stood behind each of the prisoners and accused them of "spying for the Nusayri regime". 

The Isis fighters then shot dead the five men. 

The Islamic State is known to carry out executions after accusing civilians of spying or not complying with their laws. 

Last month, the terror group executed 18 Syrian soldiers in the historic city of Palmyra.

Isis meted out punishments in the form of beheading, stoning, throwing victims from high towers and sometimes even dragging them by vehicles.
