With most of Fallujah under the control of Iraqi and American forces, new fighting is being reported elsewhere across the country.

With fighting in Fallujah, west of Baghdad, all but over, U.S. and Iraqi forces have begun focusing their attention on other trouble spots across Iraq.

North of Baghdad in Mosul, Iraq's third-largest city, Iraqi and American forces recaptured two police stations that had been overrun by insurgents in battles that left six Iraqi National Guardsmen dead. Last week, nine police stations were attacked by insurgents who stole flak jackets, weapons, and vehicles.

Officials with Iraq's Interior Ministry say calm is returning to Mosul after several days of violence.

Elsewhere in northern Iraq, U.S. forces fired missiles at suspected insurgent strongholds in the city of Baiji. American ground forces then moved into the center of the city, which is a key route for gasoline and kerosene tankers from Turkey.

In Fallujah, only small pockets of resistance continue, with Iraqi and American forces in control of most of the rebellious city. Interior Ministry officials say more than 1,000 insurgents were killed during almost one week of fighting.

Late Saturday, U.S. forces dropped four 2,000 pound bunker busting bombs on what was described as a huge underground complex used by insurgents in Fallujah. The complex was said to be about 400 meters by 300 meters and lined with tunnels.

In the meantime, relief workers near Fallujah say they are ready to start providing much needed water, food, medicines and other supplies to the thousands of residents in Fallujah displaced by the battle.

For six days there has been no electricity or running water in the city. Even so, senior officials with Iraq's Health Ministry say reports of a possible humanitarian crisis in Fallujah are groundless. Saturday, officials with Iraqs Red Crescent said a disaster was unfolding in Fallujah.

Thousands of residents who fled the city are living in makeshift accommodations in tents outside Fallujah. Interior Ministry officials say they believe aid workers will be allowed to start delivering supplies to the city by Monday.
