BEIRUT: Daesh has executed over 3,000 people in Syria, including hundreds of civilians, in the year since it declared its self-described “caliphate.”

The Syrian Observatory for Human Rights, a Britain-based group monitoring Syria’s conflict, said it had documented 3,027 executions by Daesh since June 29, 2014.

Among those executed are 1,787 civilians, including 74 children, said the Observatory. Members of Sunni Shaitat tribe account for around half of the civilians murdered.

Daesh killed 930 members of the clan in Deir Ez Zor last year after they rose up against the extremist group.

The toll also includes recent mass killings by Daesh in the Syrian Kurdish town of Kobani, which the terror group re-entered briefly this week after being expelled in January.

The monitor said it had counted at least 223 executions in the border town this week. The Observatory also documented 216 Daesh executions of rival rebel factions and Kurdish fighters, as well as the executions of nearly 900 regime forces.

Daesh has also executed 143 of its own members it accused of crimes including spying, many of them captured as they were trying to desert the group, the Observatory said.

And at least 8,000 Daesh militants have been killed in battles and US-led airstrikes, added the monitor.
