BAGHDAD - At least six people were killed on Saturday when three mortar bombs hit a Shi'ite Muslim village near the Iraqi city of Baquba, 65 km (40 miles) northeast of Baghdad, police said.A woman and a child were among the victims, five of whom belonged to the same family, the police said, adding that the assailants might have been aiming at a nearby police station.Sunni Muslim insurgents often target the security forces, as well as Shi'ite civilians and Sunni tribal militiamen paid by the Shi'ite-led government to combat al-Qaida-linked groups.Violence in Iraq climbed back to its highest level in five years in 2013, when nearly 9,000 people were killed, most of them civilians, according to the United Nations.
