A suicide bomber killed 15 people and wounded 10 when he blew himself up at a funeral ceremony in the northern Iraqi city of Baiji today, a security official said.
The attack is the latest in a spate of deadly bombings in Iraq's northern provinces, where the US military says al Qaeda militants have regrouped after being forced out of other areas.
The bomber walked into a tent where residents were mourning the death of a relative of a provincial official.
Baiji, home to Iraq's biggest oil refinery, has been the scene of a number of bombings in the past few months. On December 25th, a suicide bomber killed more than 20 people in the city, 180 km north of Baghdad.
The commander of US forces in northern Iraq, Major-General Mark Hertling, said last month that Sunni Islamist al-Qaeda was regrouping in northern Iraq after being pushed out of Baghdad and western Anbar province and was still capable of launching "spectacular attacks".
