A suicide bomber blew himself up inside a funeral tent Monday in a predominantly Sunni village north of Baghdad, killing at least 12 people and wounding 17. It was the third such bombing in Sunni areas in as many days. Nobody claimed responsibility, but it bore the hallmarks of al-Qaida in Iraq, which has been trying to derail a movement that has seen Sunnis join forces with the US against the terror network. The attacker detonated his explosives belt amid mourners in the Hajaj village on the outskirts of Tikrit, Saddam Hussein's hometown some 130 kilometers north of Baghdad, a police officer said, speaking on condition of anonymity because of security concerns. Police said at least 12 people were killed and 17 wounded.
