Suspected communist guerrillas killed 10 army soldiers who were returning to their camp in the central Philippines, officials said Wednesday. A nine-year-old boy also was killed in the crossfire Tuesday when the New People's Army guerrillas detonated landmines then opened fire on the soldiers near where villagers were swimming in a river in Northern Samar province, regional military commander Lt. Gen. Ralph Villanueva was quoted as saying by the Associated Press. Two soldiers were wounded in the ambush, which took place near a rice field in remote Catubig town. The guerrillas seized at least 11 assault rifles and grenade launchers from the slain and wounded soldiers, he said.
