Baghdad  - A tribal police member was killed Friday and another four members were injured when a bomb struck their car in Diyala province, security sources said.

The tribal police members were stopping a car when the blast occurred, the source told the Voices of Iraq (VOI) news agency, without giving further details.

Tribal police, also known as Awakening Councils, are Sunni tribe members who collaborated with the US forces to fight al-Qaeda militants in Iraq and who now take part in security duties alongside Iraqi and US forces. (dpa)
