A man died while another was seriously injured in what police said was an explosion triggered by a vintage bomb in Mandaluyong City before noon Tuesday, radio dzMM reported.
Senior Supt. Carlos de Sagun, city police chief, identified the fatality as Lawrence Garcia. He said that Garcia expired while undergoing treatment at a local hospital.
The other victim, Guillermo Enove, suffered serious injuries and is in critical condition.
Police said the two were injured after a World War II-type bomb exploded while it was being dismantled at a construction site in Barangay Barangka Ibaba.
The explosion took place at the abandoned Noah's Ark building, which stands at a bridge project between Mandaluyong and Makati City.
Police said workers found three bombs at the construction site and attempted to dismantle them with an acetylene torch.
They were successful with the first. The second, however, went off when flames touched it.
Bomb experts said the site is now secured. With reports from Edwin Sevidal, radio dzMM
