Suicide blasts and several shootings across Iraq have killed at least 41 people.
Police say a suicide bomber in Tal Afar, north of Baghdad, on Monday killed at least 20 people and wounded 17 others. In Ramadi, in western Anbar province, a suicide car bomb killed 13 people. Gunbattles killed several other people across the country.
Officials also said that several bodies showing signs of torture were found in Baghdad.
The U.S. military announced that two coalition soldiers were killed Sunday in Baghdad, one in a roadside bomb blast and another in a gunbattle.
In Washington, the U.S. military defended the detention of an Iraqi photographer working for the Associated Press, saying there were indications he had strong ties to insurgents.
A Pentagon spokesman said there was sufficient evidence to continue holding Bilal Hussein, but did not release details about the evidence.
Spokesman Bryan Whitman said three review panels had reviewed his case and each had determined he was a security threat.
On Tuesday, The Associate Press called on the military to either charge or release the photographer, who has been detained for five months.
