Insurgents bent on destabilizing Iraq killed at least 23 people in eight separate attacks on Sunday, including five kidnapped Iraqi soldiers and an 8-year-old child, officials said. According to AP, the boldest attack was near the northern Iraqi city of Mosul, where militants set up a fake security checkpoint, captured five soldiers and shot them dead, a police officer said. The soldiers were dressed in civilian clothes and returning to base in a taxi, he added. Inside Mosul, other gunmen in a speeding car shot and killed a grocer, he said, adding that the motive was not immediately clear. Another police officer said a car bomb exploded as a judge drove past in the northern town of Balad, killing three nurses and a man who had been walking nearby. Thirteen other people were wounded, including the judge, his brother and the driver, he added. In the town of Madain, about 25 kilometers (15 miles) southeast of Baghdad, a car bomb explosion killed four other civilians and wounded 12, another police officer said. Also Sunday, a bomb exploded near a policeman's house near the city of Baqouba, killing his 8-year old son and wounding 11 other people, police said. The policeman was unharmed. Baqouba is about 60 kilometers (35 miles) northeast of Baghdad. Five medical officials confirmed the casualty figures.
