ISIS has killed at least 128 people in a Syrian town deep inside regime-held territory, a human rights monitor has said. Government forces managed to retake Al-Qaryatayn over the weekend, the Syrian Observatory for Human Rights (SOHR) confirmed on Monday.
Rumours of execution-style killings of captured soldiers or civilians suspected of links to the government had not previously been verified.
Al-Qaryatayn, some 300 kilometres (190 miles) from one of Isis’s strongholds of Deir Ezzor, was recaptured by militants in an unexpected attack far from the front-line fighting earlier this month.
