Ten Iraqis have been killed and 38 injured, in continuing clashes between US occupation forces and resistance fighters in Falluja following a US attempt to enter the city on Saturday. Most of the injured are civilians, who were trying to flee the site of the clashes, particularly those bombed by US occupation forces earlier, Dr Rafya al-Isawi, director of Falluja hospital, told Aljazeera. "People and officials of Falluja have questioned the reasons behind the attempt by six US military vehicles to enter the city on Saturday morning, considering it a provocative act against them," our correspondent Husayn Dali reported. Tension "An atmosphere of high tension prevails among people of Falluja due to frequent US bombardment of Iraqi houses on the outskirts of the city," Dali said. "While US forces claim the houses belong to armed men of al-Zarqawi group, people and officials of Falluja vehemently deny this," he reported. Earlier, United States military aircraft were seen bombarding sectors of Falluja after a mortar barrage, the correspondent said. A number of houses in the al-Askari sector of the city were hit, he reported. **Aerial bombing*** He said the aerial bombardment was preceded by mortar shelling. Falluja residents said they were surprised their district was targeted, as it was located far away from the site of earlier fighting. The latest air strike comes on a day that saw fierce clashes between US occupation troops and resistance fighters in and around the city. Earlier, three Iraqis were killed and 15 others wounded in a foiled attempt by US occupation forces to enter Falluja on Saturday morning.
