Two people were killed and three others wounded when gunmen opened fire at a taxi in western Baghdad on Friday, police said.

"Unknown armed men attacked four civil defense members shortly after they got on a taxi in Baghdad's neighborhood of Ameriyah, two of them were killed and another two and the taxi driver wounded," Captain Ahmed Abdullah from Baghdad police told Xinhua.

Insurgents frequently ambushed Iraqi security forces and government employees in a bid to cripple the Shiite-dominated government formed in late April.
