BAGHDAD, April 9 (Xinhua) -- At least two security forces members were killed and seven others were injured Monday in a clash with four suicide bombers from the extremist Islamic State (IS) group in the western Iraqi province of Anbar, a local security source said.

The attack occurred before dawn when the security forces and allied paramilitary Hashd Shaabi groups fought with the suicide bombers at the al-Askari neighborhood in the town of Haditha, some 200 km northwest of the Iraqi capital Baghdad, leaving three IS militants killed, Abdul-Rahman al-Hadithi, a local Hashd Shaabi leader, told Xinhua by telephone.

At that time, a fourth suicide bomber reached a security force and blew up his explosive vest, killing two security members and wounding seven others, Hadithi said.
