Authorities said Friday at least 90 people have been injured in street battles between police and armed fighters from radical Shi'ite cleric Moqtada al-Sadr's Mahdi Army. In other violence, Iraqi authorities say mortar fire in the town of Balad killed at least nine people and wounded several others. Police say several mortar rounds hit Balad Friday, raising fears of a new round of sectarian violence in the mainly Shi'ite Muslim town, in the Sunni Arab heartland north of Baghdad. Nearly 100 people were killed in Balad in a recent wave of sectarian violence triggered by the killing of 19 Shi'ite workers last Friday. Thursday, U.S. military spokesman Major-General William Caldwell said violence in the Iraqi capital has increased 22 percent in the first three weeks of the Muslim holy month of Ramadan. He called the results of a highly-touted security operation in Baghdad "disheartening." Some information for this report was provided by AFP and Reuters. .
