The ISIS group killed 116 people it suspected of collaborating with the Syrian regime in Al-Qaryatayn this month before losing the desert town to government forces, a monitor said Monday.
"ISIS has over a period of 20 days executed at least 116 civilians in reprisal killings, accusing them of collaboration with regime forces," said Rami Abdel Rahman, head of the Britain-based Syrian Observatory for Human Rights monitor.
Regime forces retook Al-Qaryatayn, which lies in the central Homs province, on Saturday, three weeks after the jihadists seized control of it.
ISIS had first occupied the town in 2015 and lost it to a Russian-backed Syria forces last year.
