BAGHDAD ø Sunni insurgents have targeted new oil wells in northern Iraq.

Officials said insurgents blew up wells at Al Khabaza oil field near Kirkuk. They said this was the first time that Al Khabaza was targeted since the U.S.-led war in Iraq in March 2003.

So far, four oil wells were set on fire in the bombings, Middle East Newsline reported. Officials said the attack was believed to have been carried out by up to 40 insurgency operatives.

At the same time, an oil pipeline in Kirkuk was blown up. The secondary pipeline was carrying oil to refineries in the city of Baiji.
