The blast ripped through the main mosque in the town of Musaib after the attacker, strapped with explosives, mingled with the some 300 worshippers inside, Agence France-Presse news agency quoted police Lieutenant Kadhim al-Shammari as saying.

Meanwhile, some 9,000 people protested in Baghdad's Shiite slum of Sadr City after Friday prayers, burning a U.S. flag and holding banners reading "No, no to the agreement." About 2,500 people held a similar rally in the southern city of Basra, according to a report by Reuters.

"I express my condolences to the Iraqi people on this grave occasion, in which they are harmed by the ... pact of shame and degradation," Sadr, whose militia has fought U.S. troops many times, said in a statement read to followers on his behalf.
