The death toll from a powerful bomb that hit a southern Philippine city rose to eight on Tuesday, police said. Police said two people, including a police officer, died overnight following the Monday blast on the island of Mindanao. At least 29 others were wounded when the bomb went off in a busy commercial street during the afternoon rush hour. The bomb went off on a major street in Cotabato City as a car carrying city administrator Cynthia Guiani-Sayadi was passing by. She escaped unhurt, but one of her bodyguards was killed.
