Three policemen and one civilian died in the 10:15 a.m. blast near a square in the commercial district of Karradah, according to authorities, who added that the 10 wounded included three policemen.
Gunmen also killed two people, including an employee of an anti-corruption commission in a drive-by shooting in Mosul, 360 kilometers northwest of Baghdad, police said.
Elsewhere in the capital, gunmen tried to break into a girls' school in the mixed Sunni-Shi'ite neighborhood of Washash, but they fled after exchanging gunfire with two guards at the school, police said. One guard was wounded.
