At least 12 people have been killed in a suicide blast in a town north of this Iraqi capital city, local media has said.
The attack took place Monday when a suicide bomber suspected to be an Al Qaeda militant drove an explosive-laden truck into a checkpoint in the town of Tarmiyah, some 30 km north of Baghdad.
Earlier reports said the blast claimed only five lives, but fresh reports reaching here Monday said 12 people were killed in the blast.
Three children and nine members of the Awakening Councils, which are backed by the US and Iraqi governments, were among the dead, an Iraqi official said.
The Awakening Councils are groups of local Sunni neighbourhood fighters, who have turned their rifles on the Al Qaeda network to provide security to their neighbourhoods.
Rifts emerged between the two sides after Al Qaeda members adopted some hardline Islamic doctrines and started indiscriminate killings against both Shia and Sunni communities.
The Awakening Councils have been credited for helping in bringing down the level of violence across Iraq by 60 percent since June 2007.
