Iraqi authorities say at least 10 people have been killed and 21 others wounded in a car bomb attack on a Shi'ite mosque in central Iraq.
Police say a suicide bomber blew himself up early Friday, as worshippers were leaving the al-Rasul al-Aadham mosque in the central town of Tuz Khurmatu, nearly 170 kilometers north of Baghdad.
Earlier Friday in the capital, Iraqi police say gunmen opened fire on a group of day laborers, killing at least three people and wounding 13 others.
The attacks come as part of a campaign of violence by insurgents that has killed more than 180 people in Iraq since Wednesday.
Separately, the U.S. military says an American soldier was killed late Thursday in an explosion in the city of Ramadi, in al-Anbar province.
