The fighting is the first major clash between al-Sadr's Imam Al-Mahdi Army and Iraqi forces which took over security in the city following an agreement last week.
The clashes began overnight when Iraqi police tried to arrest a group of al-Sadr supporters.
U.S. forces were not involved in the fighting.
Under last week's agreement, al-Sadr militiamen pulled back from the rest of Al-Najaf but reportedly remained holed up at several locations in the city center.
The agreement was reached by local Shi'a leaders to end weeks of fighting between al-Sadr supporters and U.S. forces.
