The military deployed hundreds of marines and ordered air force planes to bombard areas on southern Jolo island Tuesday to halt attacks by followers of a jailed Muslim rebel leader that triggered clashes in which at least 17 soldiers were killed, officials said. Lt. Gen. Alberto Braganza, commander of the military's Southern Command, estimated that up to 30 gunmen loyal to Nur Misuari may have also been killed in the fighting in Panamao and other outlying towns. Up to 600 marines sailed from southern Zamboanga city to reinforce troops on Jolo. Air force helicopters and planes were also dispatched to help bombard gunmen holed up in Panamao.
