IS executes 30 tribesmen in Iraq

The Islamic State militant group executed more than 30 tribesmen in western Iraq on Wednesday, as government forces continue their offensive against the extremist militants across the country, security sources said.

IS captured more than 40 tribesmen from the Sunni tribe of Albu Nimer in the militant seized town of Heet, some 160 km west of the Iraqi capital Baghdad.

The group executed their detainees after accusing them of collaborating with the security forces against IS militants, a provincial security source said.

Dozens of residents who were forced to witness the executions, the source said.

The IS group has seized around 80 percent of Iraq's largest province of Anbar and is trying to advance toward Baghdad, but several counter attacks by the security forces and Shiite militias have pushed them away from areas west of the capital, which contains a large Shiite population and is heavily fortified by security forces and Shiite militias.
