25. Terrorists Against Policemen in Philippines, 1987: 19 Casualties, 140 Wounded
Zamboanga City, 530 miles south of the Philippine capital of Manila, has seen more than its fair share of conflict and violence. In 1987, a group of recruits to the police academy fell ill after going for a run. Immediate reports claimed that they had suffered heat stroke, but later documents pointed to poisoning.
In an area plagued by gang activity and sectarian violence, a terrorist group poisoned the water supply at the police constabulary with a pesticide. Of the recruits who fell ill, 19 died. Many reported that an unidentified person had given them ice bags, which were probably also laced with the pesticide.
