BAGHDAD – Militants downed an Iraqi army helicopter Thursday and killed nearly a dozen security forces in overnight clashes, a regional official said, in what appeared to be an Al-Qaeda surge to retake one of its former strongholds in Iraq.



The fighting around the town of Hadid, about 10 kilometers north of the Diyala provincial capital of Baqouba, was in its third and deadliest day.



It comes on the heels of a warning last weekend by Al-Qaeda’s leader in Iraq to push back into areas it was forced out of by the US military.



That threat was followed by a wave of violence that killed 115 people in the country’s deadliest day in more than two years — an assault for which Al-Qaeda claimed responsibility.



Diyala provincial spokesman Salih Ebressim Khalil said militants targeted the Iraqi army helicopter, killing one soldier, wounding another and forcing it to make an emergency landing. The rest of the crew was unharmed.



Overnight clashes left 11 federal policemen dead, Khalil said.



He said the clashes began Tuesday at a security checkpoint in a rural area near Hadid, located about 72 kilometers (45 miles) northeast of Baghdad.



Federal police quickly locked down the area, but the fighting continued.



Diyala is a predominantly Sunni province that is sandwiched between Baghdad and the Iranian border. It has a large Shiite population, and well as pockets of ethnic Kurds, and long has been a battleground for Sunni insurgents trying to assert control. Its remote rural areas have served as a safe haven for insurgents, and posed a major challenge to Iraqi security forces.



In a statement posted on a militant site last Saturday, local Al-Qaeda leader Abu Bakr Al-Baghdadi announced a new campaign dubbed “Breaking the Walls.” He said it sought to undermine the nation’s weakened Shiite-led government by realigning with Sunni tribes, and return to areas it was driven from before the American military withdrew from Iraq last December. – AFP
