Huge blasts at a suburban Manila police ammunition dump injured at least 107 people, damaged several buildings and homes and set off security jitters in a capital long wary of possible terror attacks and a coup, officials said. Police ruled out sabotage or terrorism.

　　Late Monday's explosions, which investigators say were apparently touched off by lightning, initially raised concerns of foul play due to swirling coup rumors linked to the monthslong political crisis hounding President Gloria Macapagal Arroyo.

　　She has been accused of rigging last year's election but has denied the allegations.

　　An ammunition bunker filled with World War II vintage bombs and homemade explosives seized from Muslim militants and fishermen was obliterated by the explosions, which also damaged nearby buildings and homes in and out of Camp Bagong Diwa, police said.

　　The blasts shattered glass windows and ripped off parts of the roof of a dormitory for drug addicts at a rehabilitation center, hurled about 30 parked vehicles away and damaged a gas station, witnesses said.

　　"Initially, I thought that the camp was under attack," said metropolitan Manila police chief Vidal Querol, who was at the camp when shock waves from the blasts shattered his windows. "We later found out that there was no hostile fire, no sabotage or terrorism."

　　The injured included 101 patients at the drug rehabilitation clinic, four elite police officers and two civilians, police said. One of the officers narrowly escaped being hit by a slab of concrete that flew several blocks from the blast site.

　　Residents living in and out of the camp recalled hearing small explosions followed by two large ones that rained debris.
