MANILA - Suspected al-Qaeda-linked militants raided a village in the southern Philippines early Saturday, killing 11 people in the country's worst militant attack on civilians in nine years. Gunmen from the extremist Abu Sayyaf group backed by renegade Muslim separatist rebels fired grenade launchers and automatic rifles on houses while residents were asleep, killing one government-armed militiaman and 10 civilians in the village of Tubigan on Basilan Island, said deputy regional police commander Sonny David. "The villagers were sleeping when the Abu Sayyaf came with their guns blazing. They spared no one, not even the children," David said. The attack came in the wake of the recent killing of an Abu Sayyaf commander and the arrest of two key members. Government forces had been told to be on alert for reprisal attacks. "It's a normal thing for them to retaliate," David said. "We're not lowering our guards, particularly at soft targets like markets, schools, churches, piers and public utility terminals." Four children were among those killed, said armed forces spokesman Lt. Col. Romeo Brawner. He corrected an earlier report that the target of the attack was the village's militia detachment. "They really attacked the villagers," he said. One of the villagers, who are mostly citrus farmers, told police he was awakened by the sound of gunfire and saw blood oozing from his body, David said. The gunmen strafed and torched at least 10 houses before escaping, David said. A 32-year-old woman and her 1-year-old daughter burned to death in their house, he said.
