More than 30 people were killed Saturday in a bomb blast in the Iraqi capital -- as Muslims began observing the Islamic holy month of Ramadan.
Iraqi officials say at least 24 others were wounded in the explosion in Baghdad's Shi'ite-dominated Sadr City neighborhood.
The U.S. military said this week it expects attacks in Iraq to increase during Ramadan. Sunni Muslims in Iraq began observing the holiday Saturday.
Shi'ites are to begin marking Ramadan on Sunday. Meanwhile, Iraqi authorities say they captured the leader of the militant group Ansar al-Sunnah. That group has claimed responsibility for bombings and for beheading hostages.
And the U.S military says three American soldiers were killed Saturday by roadside bombs. Officials in Denmark say one Danish soldier was killed and eight others wounded by a roadside bomb.
Separately, U.S. officials say an American working as a contractor for the State Department was killed in a rocket attack in the southern city of Basra Friday.
