http://www.aljazeera.com/cgi-bin/news_service/middle_east_full_story.asp?service_id=1591One soldier in the 9000-strong force under Polish command in central Iraq was killed in the fighting, according to Aljazeera's correspondent in the city. Explosions were heard over different parts of the city as the rival forces traded fire for half an hour. Witnesses and hospital staff said five civilians - four Iraqis and one Iranian - and five members of al-Sadr's Mahdi army were wounded in the clashes.
After the firing which erupted before Friday's prayers, the Mahdi army fighters said they had beaten back an assault by occupation forces. The occupation in a statement said at about 12:10 (0810 GMT), a convoy was attacked near the city hall. "The patrol returned fire," it said.
City hall is located near the office of an al-Sadr religious foundation and the al-Mukhayyam mosque controlled by his loyalists.
US-led occupation forces have threatened to retake Karbala, located 110 km south of Baghdad, from al-Sadr loyalists who seized the city early this month. An uneasy standoff had been in effect over the past few days, with Iraqi police hunkered down around official buildings and patrolling only near holy sites while al-Sadr's Mahdi militia was deployed near the cleric's local headquarters.
Al-Sadr also urged Najaf residents to create committees to run their city. "It is up to you to build your Islamic capital," he said. "We should be united for one ultimate goal, to liberate our country and remove the filth from Iraq." The congregation chanted "Long live Sadr" and denounced not only the occupation forces but the US-appointed Iraqi Governing Council, saying "America and the Council are infidels".
