Among the targets was a police checkpoint in the town of Taji, about 20 kilometers north of the capital, where more than 10 people were killed and nearly two dozen wounded.
Authorities say the police in Taji were investigating the site of a roadside bomb blast when a suicide attacker walked into the crowd and detonated his explosives.

Last week, nearly 30 people were killed in an attack against a police station in the northern city of Kirkuk.
