He added that 18 others were wounded in the attack. In the northern town of Tuz Khormato, a series of bomb blasts rocked residential areas, killing at least four civilians and wounding seven others, said Shalal Abdol, the mayor of the town, which is located about 200 kilometers (130 miles) north of Baghdad.

Another civilian was killed and three wounded in the northeastern suburb of Husseiniyah, and a lawyer was shot dead while driving through the eastern New Baghdad neighborhood, police added.
