U.S. troops have captured 34 Iraqis, including 10 wanted for making explosive devices to attack coalition forces, the military said Tuesday. South of Baghdad, a roadside bomb killed three Iraqi National Guardsmen. Soldiers from the 1st Infantry Division detained seven members of a car bomb-making cell Monday evening in As Siniyah, about 240 kilometers (150 miles) north of Baghdad. Another seven people, including three suspects wanted for making roadside bombs, were captured during raids Monday in Tikrit, Saddam Hussein's hometown, about 130 kilometers (80 miles) north of Baghdad. During a search of one house, soldiers found three homemade bombs, a weapon that has been used to deadly effect against hundreds of American and Iraqi soldiers since the onset of the war last year. Several hundred U.S. and Iraqi forces arrested 20 suspected militants Sunday in the southern Baghdad district of Rashid following a short firefight, the military said in a statement Tuesday. In the roadside bombing, the Iraqi National Guardsmen were patrolling an area near Jebala, about 65 kilometers (40 miles) south of Baghdad, when the attack occurred, an Iraqi National Guard official said on condition of anonymity.
