Bagatsing was one of the survivors of the Plaza Miranda bombing on August 21 , 1971 , which was at that time considered one of the bloodiest political massacres in Philippine history . Nine were killed and almost a hundred more — including Bagatsing — were wounded after two grenades were thrown on the stage by still-unknown assailants . The public rally was meant to be Bagatsing 's official proclamation as mayoral candidate for Manila of the opposition Liberal Party . He was among the three most critically injured , along with Senators Jovito Salonga and Sergio Osmeña , Jr. , who nearly lost their lives as they were front and center on the elevated platform , which was the epicenter of the bomb blast . Others who were also hurt included prominent Philippine politicians such as Gerardo Roxas , Eva Estrada-Kalaw , Genaro Magsaysay , Ramon Mitra , Eddie Ilarde , Salipada Pendatun , Roberto Oca Jr. and John Osmeña
