TARMIYAH - Gunmen armed with silenced weapons attacked a house in a town north of Baghdad on Wednesday, killing seven members of a family, including three young children, security officials and a medic said. Two members of the family, including one of the dead, belonged to the anti-Qaeda Sahwa militia force, made up of Sunni tribesmen who resisted the militant group and helped turn the tide of the war in Iraq. The attack in the town of Tarmiyah took place about 4:00 am (0100 GMT).
