Special report: Tension accelerates in Iraq

    TIKRIT, Iraq, Aug. 6 (Xinhua) -- Unknown gunmen attacked a convoy of trucks near a northern Iraqi town on Sunday, setting ablaze two trucks and killing two Iraqi drivers, a local police source told Xinhua.

    The armed men opened fire at the convoy carrying supplies for U.S. troops on the main road near Ishaqi, a small town about 110 km north of Baghdad, said the source of nearby Samarra City.

    In March, the town witnessed the horrific images of 11 Iraqi civilians who were killed after being captured by U.S. soldiers in a raid.

    But the U.S. military denied the responsibility after a military investigation, saying that U.S. forces were following rules of engagement. Enditem
