Special report: Tension escalates in Iraq

    FALLUJAH, Iraq, Sept. 17 (Xinhua) -- A series of blasts, including a car bomb and a motorcycle bomb targeted American troops and Iraqi police in the restive city of Fallujah on Sunday, local police source said.

    "Four roadside bombs, a car bomb and a motorcycle bomb detonated in several parts of the city before midday, targeting the U.S. troops and Iraqi police," the source told Xinhua on condition of anonymity.

    The blasts followed by gunfight and mortar barrage between gunmen and U.S. troops in three of Fallujah neighborhoods, the source said.

    The source said there is no word on casualties as the U.S.troops used loudspeakers to announce curfew while U.S. soldiers took positions on roofs of high buildings and U.S helicopters flew over the battle spots.

    Sunni-dominated Fallujah has frequently witnessed insurgent attacks against the U.S. and Iraqi government forces despite U.S.-Iraqi military operations in the city to stamp out insurgency and hunting foreign fighters. Enditem
