A new round of fighting has erupted in the Iraqi holy city of Najaf between U.S. forces and Iraqi Shi'ite militiamen holed up in a religious shrine.
The fighting broke out after U.S. tanks took up positions about 800 meters from the Imam Ali shrine. U.S. warplanes pounded nearby targets during the early-morning hours, Sunday, hitting militiamen in Najaf's cemetery district.
The U.S. military has not commented on the battle, other than to say fighting is ongoing.
Talks in Najaf between Shi'ite religious leaders and rebel cleric Moqtada al-Sadr's militias are said to remain at an impasse.
Separately, the U.S. military says five U.S. military personnel have been killed in separate incidents in Iraq. Also, two Iraqis died in a car bombing, north of Baghdad.
