Baghdad - A female suicide bomber killed seven tribal police members on Monday in Iraq's Baquba city, witnesses said.
The bomber detonated herself in the midst of a tribal police checkpoint in al-Atibaa street in the centre of Baquba, 60 kilometres north of Baghdad, witnesses told Deutsche Presse-Agentur, dpa.
Eight people, including civilians and tribal police, were wounded in the attack.
Tribal police are also known as the Awakening Councils, which are members of Sunni tribes who coordinated with the US forces to fight al-Qaeda militants in Iraq.
