BAQOUBA, Iraq -- A suicide bomber struck a U.S.-promoted reconciliation meeting of Shiite and Sunni tribal sheiks as they were washing their hands or sipping tea Monday, killing at least 15 people, including the city's police chief, and wounding about 30 others.
Two U.S. soldiers also were wounded in the 8:30 p.m. blast at a Shiite mosque in Baqouba, a former al-Qaida stronghold about 35 miles northeast of Baghdad, according to U.S. and Iraqi officials, who gave the overall casualty toll.
The brazen attack, which bore the hallmarks of al-Qaida in Iraq, represented a major challenge to U.S. efforts to bring together Shiites and Sunnis here in Diyala province, scene of some of the bitterest fighting in Iraq.
About two hours after the blast, U.S. soldiers at nearby Camp Warhorse fired artillery rounds at suspected insurgent positions near Baqouba. There were no reports of damage or casualties.
Witnesses and officials said the bomber struck when most of the victims were in the mosque courtyard cleaning their hands or drinking tea during Iftar, the daily meal in which Muslims break their sunrise-to-sunset fast during the holy month of Ramadan.
Security guards approached a man after noticing him walking rapidly through the courtyard. As the guards challenged him, the man detonated an explosive belt, setting off the devastating blast, said police Maj. Salah al-Jurani.
Al-Jurani said he believed provincial Gov. Raad Rashid al-Tamimi was the intended target. The governor was wounded and his driver was killed, al-Jurani said.
The dead also included Baqouba's police chief, Brig. Gen. Ali Dalyan, and the Diyala provincial operations chief, Brig. Gen. Najib al-Taie, according to security officials. They spoke on condition of anonymity because they were not supposed to release the information. Also wounded was the governor's brother, Sheik Mazin Rashid al-Tamimi, who has spearheaded Sunni-Shiite reconciliation efforts in the province.
"We've tried to persuade the tribes to oust terrorists from their areas because it's a disaster when the tribes cooperate with and provide refuge to al-Qaida," Sheik Mazin said.
U.S. officials have accelerated efforts to reconcile Sunni and Shiite tribes in Diyala after American soldiers gained control of Baqouba, the provincial capital, in fighting last summer.
The United States announced this month that top leaders of 19 of the 25 major tribes in Diyala -- 13 Sunni and six Shiite -- had agreed to end sectarian violence and support the government, although the province remains one of the most dangerous in the country with frequent kidnappings and armed clashes.
Also Monday, an American soldier was killed by hostile fire in Salahuddin province north of Baghdad, the U.S. military said.
