Two suicide bombers detonated explosives-rigged vehicles on Monday in a town north of the Iraqi capital that has battled jihadist militants, killing 10 people, police and a doctor said.
The blasts in Dhuluiyah — which was overrun by militants but drove them out and then put up fierce resistance when they sought to take it a second time — also wounded more than 30 people, the sources said.
The first blast breached a barrier surrounding the Jubur area — which held out against the renewed militant push for the town — while the second bombing struck inside.
There was no immediate claim for the attack, but suicide bombings are almost exclusively carried out by Sunni extremists, including those from the Islamic State (IS) jihadist group, which spearheaded a major offensive that has overrun swathes of territory since it was launched in June.
The initial militant onslaught swept security forces aside, but Baghdad won its first major offensive victory of the conflict late last month, when federal troops, Shiite militiamen and Kurdish fighters broke the 11-week jihadist siege of the town of Amerli.
But major areas remain outside of government control and there is no end to the conflict in sight.
