Evidence has emerged of another Islamic State militant group (ISIS) mass execution, this time in the Syrian Christian desert town of Al-Qaryatain. The militant group killed at least 116 civilians in executions committed in the days before the Syrian regime recaptured the town, according to the Syrian Observatory for Human Rights (SOHR), a U.K.-based monitoring group with an extensive network of contacts in Syria. “ISIS has over a period of 20 days executed at least 116 civilians in reprisal killings, accusing them of collaboration with regime forces,” SOHR chief Rami Abdelrahman told the Agence France-Presse news agency.
