Sources from Iraq are confirming that a suicide attack on a former Iraqi lawmaker’s house killed at least six tribal militiamen and wounded several others.

The suicide attack was carried out on the night between Tuesday and Wednesday in Asdira, a Sunni Muslim village.

No group has claimed responsibility for the attack but Islamic State militants operate in the area.

According to the first information received, a militant wearing a suicide vest blew himself up just after midnight at Adnan al-Ganam’s house in the village of Asdira, Colonel Khalil al-Sahn, the police chief of surrounding Shirqat district, told Reuters.

Those killed are believed to be members of the Tribal Mobilisation Forces, a network of Sunni militias that back the government in its fight against Islamic State, he said.

The village is north of Tikrit, the capital of Iraq’s Salahaddin province.
