Two separate attacks against Iraqi security forces killed three people and wounded 18 others on Tuesday, officials said.
A bomb in a parked car exploded around noon near an Iraqi army checkpoint in the northern city of Mosul, killing a soldier and a bystander, a police officer said. Twelve other passers-by were wounded in the attack.
Sunni-dominated Mosul, located 225 miles (360 kilometers) northwest of Baghdad, was a major haven for al-Qaida in Iraq and other insurgent groups several years ago even as militant activity declined elsewhere.
Two hours earlier, a police patrol hit a roadside bomb in Baghdad's eastern neighborhood of Mashtal, killing a bystander and wounding six others, another police officer said.
