An Iraqi Army officer and a gunman were killed in fighting in western Baghdad on Thursday, an Interior Ministry source said.
The clash erupted when two gunmen were about to hurl a hand grenade at a passing Iraqi Army vehicle near al-Rwwad intersection in Mansour district, prompting the soldiers to trade fire with the attackers, the source told Xinhua on condition of anonymity, reported Xinhua.
The clash resulted in the killing of an Army officer and a gunman, while the soldiers arrested another gunman, the source said.
Three civilians were also wounded by the fire exchange, the source added.
Despite security gains in recent months in Iraq, there are still sporadic bombings targeting U.S. troops, Iraqi security forces and civilians, which shape setback to the Iraqi government.
