IS execute over 90 in Syria in past month

The Islamic State jihadist group has executed more than 90 people - a third of them civilians - over the past month in Syria, a monitoring group says.

The Syrian Observatory for Human Rights said 32 civilians were among 91 people executed for "crimes" in the jihadist group's self-proclaimed caliphate between July 29 and August 29.

The toll included IS members, rebel fighters and forces loyal to President Bashar al-Assad.

Witchcraft, homosexual acts and working with the US-led coalition fighting IS in Iraq and Syria are among "crimes" punishable by death for the group.

Since it announced its "caliphate" in June 2014, IS

has swept across Syria, seizing swathes of land in central Hama and Homs provinces, Deir Ezzor and Hasakah in the east, and the north's Raqa and Aleppo.

According to the Britain-based Observatory, IS have executed 3156 people - including 1841 civilians - in Syria since the caliphate was announced.

IS has become notorious for its gruesome displays of violence, including beheadings, stoning and pushing victims off rooftops.
