A suicide bomber blew himself up Sunday in a northern Iraqi cafe, killing at least 13 people and wounding 23 others in the town of Tuz Khurmatu.
Elsewhere, Iraqi officials say gunmen who kidnapped 30 sports officials have freed six of them in Baghdad. There was no word on the other hostages, including Iraq's Olympic Committee chief.
Meanwhile, insurgents raided the detention wing of a hospital northeast of Baghdad and freed several wounded comrades. Four security men were killed in the attack.
In southern Iraq, British officials said gunmen killed a British soldier in Basra - the country's first military death in Iraq since late May. Separately, two British soldiers were wounded by a roadside bomb.
In Kirkuk, U.S. and Iraqi forces killed one gunman and captured two after the gunmen ambushed and wounded an Iraqi security officer.
