At least 20 people have been killed in a bomb attack in the Iraqi city of Fallujah, west of Baghdad.
Another 20 people were wounded when the bomber, wearing a suicide explosives vest, detonated a device near a queue of about 150 young men at a police recruitment centre.
The city, which lies 50km west of Baghdad, is in restive Anbar province - a stronghold of the Sunni Arab insurgency.
Recruitment centres for Iraqi security forces are common targets for such attacks, which are mostly blamed on Sunni Islamist al-Qaeda.
