Islamic State suicide bombers killed at least six security personnel on Saturday in a town near the extremist militia’s stronghold in western Iraq, a police official said.
At least 14 security troops and allied tribal fighters were injured in the attack, which targeted a residential and government complex in the town of Amiriyat Fallujah, south of Fallujah, the Islamic State stronghold in the mostly Sunni western province of Anbar.
Anbar police spokesman Yasser al-Dulaimi told dpa that security forces killed nine of the attackers, who had earlier sneaked into Amiriyat Fallujah, around 50 kilometres west of the capital Baghdad.
The town houses government institutions relocated from Ramadi, the capital city of Anbar one controlled by Islamic State.
In December 2015, Iraq regained Ramadi from the radical Sunni group after it had held the city for seven months.
In recent weeks, Islamic State has stepped up its attacks in Iraq.
On Wednesday, the al-Qaeda-breakaway group claimed responsibility for a wave of bombings in Baghdad, which killed more than 90 people, marking Iraq's deadliest day so far this year.
Islamic State still controls areas in Iraq's Sunni heartland in the west and north.
