Female suicide bombers
The authorities in Iraq said a female suicide bomber has killed eight people and wounded more than 20 others.
The woman detonated her explosives near a military patrol or checkpoint in the town of Baquba, a frequent flashpoint.
Those killed were reported to be local Sunni troops recruited to work with US and Iraqi forces.
Earlier this month, another female suicide bomber struck in a busy market near Baquba, killing nine people and wounding many more.
Correspondents said women are less likely to attract the attention of male security guards because of Arab conventions on relations between men and women.
