Bomb attacks across Iraq kill 30, wound nearly 100 BAGHDAD (Reuters) - Car bombs killed at least 30 people across Iraq on Sunday and wounded nearly a hundred, with attackers mainly targeting busy commercial streets in the capital, police sources said. The deadliest attack took place in the predominantly Shi'ite Muslim district of Bayaa in Baghdad when a bomb in a parked vehicle detonated near car workshops, killing seven and wounding 14, the sources said. The last large set of bombings was on November 21 north of the capital. Since then, there has been a steady flow of smaller attacks. No group immediately claimed responsibility for Sunday's bombings but al Qaeda has increased its grip on areas across the country since the escalation of the crisis in neighboring Syria and the withdrawal of U.S. troops from Iraq in 2011. At least 94 people were wounded in Sunday's attacks. In one, a car bomb exploded in a busy square in central Baghdad, killing at least five people and wounding 15, police said. In Radhwaniya, a predominantly Sunni area in the capital, a roadside bomb killed two people and wounded eight, police said. There were other attacks in Baghdad's mainly Shi'ite districts of Amel, Ghadir, Sadr City and Hussainiya. In Baquba, 65 km (40 miles) northeast of Baghdad, a bomb in a parked car blew up inside a market killing two people and wounding seven, police said.
