Members of the Islamic State group have 'executed' 19 civilians including two children in a village held by anti-jihadists in eastern Syria, the Syrian Observatory for Human Rights said Saturday.

"IS fighters entered Jazrat al-Boushams village on Friday evening and executed 19 civilians, including two women and two children, with bullets to the head before torching the corpses," Rami Abdel Rahman of the Britain-based monitor told AFP.
