20 killed in Iraq attacks
A pre-dawn raid by the US military on a suspected Al-Qaeda hideout southwest of Baghdad also left five alleged insurgents and a woman dead.
The violence flared as Iraq's Sunni Arab and Kurdish leaders warned that the long-running dispute over the fate of Prime Minister Ibrahim Jaafari was unlikely to be resolved before parliament convenes on Monday.
Iraqi leaders have failed to agree on the Shia nomination of Jaafari to remain premier, four months after a landmark election to choose the country's first permanent post-Saddam Hussein government.
The country has been engulfed in sectarian violence that has left hundreds dead since the bombing of a major Shia shrine in Samarra in February.
