A suicide bomber targeted a reconciliation meeting of Shiite and Sunni tribal leaders in Baqouba on Monday, killing at least seven people, including the city's police chief, security officials said.
The attacker blew himself up about 8:30 p.m. as guards searched him at the entrance to a Shiite mosque where the meeting was being held.
Baqouba's police chief Brig. Gen. Ali Dalyan and the Diyala provincial operations chief Brig. Gen. Najib al-Taie were near the bomber and were among the seven killed, according to the security officials.
The officials, who spoke on condition of anonymity because they weren't authorized to release the information, also said 17 people were wounded, including several other senior provincial leaders.
