Eight members of a pro-Iran militia were killed by unknown assailants in Syria’s al-Mayadeen city in the Deir Ezzor region. The assailants attacked the headquarters of the “Syrian Revolutionary Guards” militia that is affiliated with Iran’s Revolutionary Guards Corps, butchering their victims with knives. Security and military forces in the region went on high alert in wake of the attack, said the Syrian Observatory for Human Rights. This was the second attack of its kind in less than 48 hours in Deir Ezzor, the so-called “capital of Iranian militias in Syria.”
