A Philippine police spokesman on Tuesday assured the public that the security situation in Metro Manila is under control, even though a bomb went off in front of the state prosecutors' building and explosives were found in a government department compound. Police Senior Superintendent Leonardo Espina said that the explosion and the recovery of the bomb are two isolated cases and there is even no need to upgrade the alert level in the capital. 'We are in full control of the situation and we have not received any report of terrorism activity here,' he said. On Sunday, an explosion rocked the compound of the Office of the Ombudsman before dawn, but no one was hurt. One day later, an improvised explosive device was found inside the compound of the Department of Agriculture, but bomb experts had it safely removed. Talks of destabilization threats surface in the capital, which had seen its share of violence in the past few years. A passenger ferry docked at Manila Bay was bombed by suspected Abu Sayyaf terrorists in 2004, killing at least 100 people on board. Light rail and bus stations were also bombed at peak hours in the past decade. The military on Tuesday joined the police in probing the blast attacks but they have yet named any suspect.
