Special report: Tension escalates in Iraq 　

    FALLUJAH, Iraq, Dec. 28 (Xinhua) -- A suicide car bomber strucka police patrol in the city of Fallujah in Iraq's western Anbar province on Sunday, killing two people and wounding seven others, a provincial police source said.

    The attack took place in the morning on the eastern entrance of Fallujah, killing a policeman and a civilian and wounding four policemen and three civilians, the source said on condition of anonymity.

    A police vehicle was damaged by the blast along with five nearby civilian cars, the source added.

    Anbar, including Fallujah, some 50 km west of Baghdad, has been relatively calm since more than a year and a half ago after Sunni tribes and anti-U.S. insurgent groups turn up against al-Qaida in Iraq network, cooperating with the U.S. troops and Iraqi security forces.
