At least 12 people were killed and 17 injured in a suicide bombing late Thursday that targeted a celebration in the city of Ramadi to mark the Prophet Mohammed's birthday, dpa reported.
A journalist with the Iraqi satellite television station al- Ittijah was among those killed in the blast. The reporter's name remains unknown.
Security sources said the bomber used an explosives belt to blow himself up at a cultural center in Ramadi, which is about 120 kilometres west of Baghdad and is the capital of al-Anbar province.
The deputy governor of the province, Hikmat Jassem, was among those injured in the blast.
Also on Thursday, gunmen linked to al-Qaeda in Iraq killed a father and his three sons in their home in the city of Baquba, some 60 kilometres north-east of Baghdad.
One of the sons was a policeman in Diyala province, but it was not clear why the family had been targeted.
Meanwhile, in the restive northern city of Mosul, a civilian was killed and nine others injured when gunmen attacked a police checkpoint.
