At least 10 people were killed and dozens wounded -- many of them soldiers or police -- in a twin bombing Monday on a southern Philippine island that is a stronghold of Islamist militants, officials said. The attack happened in Jolo in Muslim-majority Sulu, where government-backed security forces have long been fighting the Abu Sayyaf group. At least five of the dead and 16 wounded were soldiers, Lieutenant General Corleto Vinluan told reporters. str-bur-amj/fox
