US / Shia clash erupts in Baghdad

Four militiamen loyal to Iraq's radical Shia cleric, Moqtada Sadr, have been killed in clashes with US forces in Baghdad overnight, Iraqi officials say. It is the first such fighting since a rebellion by supporters of the cleric ended more than a year ago. The US military confirmed it had fought "anti-Iraqi forces" in eastern Baghdad. Meanwhile, at least nine people have been killed in a bomb attack on police in Baghdad, while two died in a market bomb in Hilla, officials said.
In another attack, at least six people were killed by a bomb at a Shia mosque in Musayyib, some 60 km (40 miles) south of Baghdad, on Sunday.
