BAGHDAD — A car bomb in a packed food market north of Baghdad killed 30 people on Thursday as a surge in violence nationwide pushed Iraq’s death toll for 2013 above 5,800. The rise in unrest has forced officials to appeal for international help in fighting the country’s worst bloodshed since 2008, just months before Iraq’s first elections in four years. Thursday’s attack comes a day after a spate of violence across the country, including a wave of bombings in the capital, killed 59 people and left more than 100 wounded, marking Iraq’s deadliest day this month. The latest explosion went off at around noon (0900 GMT) near a cafe in a food market in the town of Saadiyah, which lies northest of Baghdad in restive ethnically-mixed Diyala province. At least 30 people were killed and 40 others wounded in the blast, according to a police colonel and a doctor, both of whom spoke on condition of anonymity. Saadiyah is populated mostly by Faylis, or Shiite Kurds, and lies within a tract of disputed territory that is claimed by both the central government and Iraq’s autonomous Kurdish region. – AFP
