Death toll in apartment explosion in upscale Manila district rises to six A telephone operator at the Taguig city police station, who declined to give her name because she was not authorised to speak to the media, said the explosion came from an appliance and was not caused by a bomb. Interior Secretary Mar Roxas, who visited the site with President Benigno Aquino III, told reporters that the building was evacuated and all possible angles were being investigated. He said a forensic examination was not yet finished. This could be an accident, this could be an explosion of chemicals. This could be anything. Let us not speculate," he said. He urged the public to refrain from speculating if the blast was linked to recent travel advisories issued by the U.S., British, Canadian and Australian governments for the restive southern Philippines, where they cited a risk of kidnappings and terrorist activities.
