FALLUJAH, Iraq, Jan. 30 (Xinhuanet) -- Gunmen attacked a house used by U.S. soldiers as a base in eastern Fallujah on Monday, witnesses said.

    "Armed men surrounded a house used by American soldiers as base and opened heavy fire for 15 minutes at about 9:00 a.m. (0600 GMT)in the Annaz area," the witnesses told Xinhua on condition of anonymity.

    The attackers destroyed the house with the U.S. soldiers inside and fled the scene, added the witnesses.

    According to them, U.S. helicopters hovered over the area firing two rockets at suspected insurgent positions, as other U.S.troops cordoned off the area.

    In separate incident, insurgents hurled 10 mortar rounds late Sunday night at the Habaniyah military base, said the sources. 

    However, the U.S. military had no immediate comment on the above information from Fallujah.

    The Sunni-dominated Fallujah, some 50 km west of Baghdad, and nearby towns, have witnessed sporadic insurgent attacks against the U.S. and Iraqi government forces despite U.S.-Iraqi military operations in the city to stamp out insurgency.  Enditem
