Amjad Youssef, one of the main perpetrators of the 2013 Tadamon massacre in Damascus during the Syrian civil war, has been arrested.

His detention followed “a successful security operation”, Interior Minister Anas Khattab announced on Friday on X.

A security source told Sana news agency that Youssef, an intelligence officer under Bashar al-Assad's government, was detained in the al-Ghab area of Hama, in Syria’s western countryside.

The massacre took place on 16 April 2013 in the Tadamon neighbourhood of Damascus.

Syrian soldiers and militiamen walked 288 people into a pit and mocked them before shooting them dead.
