Onlookers were left stunned by the suicide attack
Fifteen people have been killed and 39 wounded by a female suicide bomber in the northern Iraqi city of Baquba.
The bomber detonated the device in front of a group of policemen at the entrance to a local government and law courts complex.
A number of civilians are said to be among the casualties.
Previous bomb attacks in the Baquba area have been blamed on Sunni insurgents said to have links with the al-Qaeda network.
Doctor Ahmed Fuad, at Baquba's hospital, was quoted by AFP news agency as saying that among those killed in the latest bombing were eight policemen, two women and one child.
Several vehicles caught fire as a result of the explosion, while some nearby buildings were damaged by the impact.
Women recruits
Baquba is the capital of the restive Diyala province - one of the most dangerous parts of Iraq.
It has seen a series of suicide bombings by women over the past year.
Security officials say al-Qaeda has recruited women bombers because they are often subjected to lighter security checks than men.
Last Tuesday more than 60 people were killed in a car bomb attack in Baghdad. The Americans blamed what they termed renegade Shia militiamen trying to incite inter-communal violence.
It was the deadliest bombing in Iraq's capital for weeks, following a security drive by Iraqi and US forces.
Despite such attacks, overall levels of violence in Iraq are at a four-year low.

A bombing in the Iraqi province of Diyala  has killed 15 people, according to local officials. The suicide bomb exploded at the entrance to a local government centre in the city of Baquba, which is one of the most deadly areas in Iraq. 39 people were also wounded by the attack.

An anonymous witness of the blast described the bomber. "I heard some of the injured people saying they saw a woman wearing a black robe blow herself up."

This attack comes after a bombing on Tuesday killed 51 people, according to local police. That bomb exploded near a bus stop in the Hurriya area, which is mainly populated with Shia Muslims. 75 people were also wounded in Tuesday's attack, which was the deadliest in the area for three months.
