Tamil Tiger supremo Velupillai Prabhakaran was on Monday shot dead by Sri Lankan special forces as he tried to stage a dramatic breakout from the Army encirclement, a military spokesman said. Prabhakaran and his top aides came out of their last hiding place in a small convoy of van and an ambulance and tried to drive out of the war zone, but were gunned down, he said. However, the Army is withholding an official announcement till a DNA test of the bodies are conducted. The Tiger chief was killed with two others, who are yet to be identified but believed to be his closest associates LTTE intelligence chief Pottu Amman and Sea Tigers' chief Soosoi. The deaths of the top LTTE leaders came a day after Tamil Tigers conceded defeat saying the decades-old battle has reached its "bitter end" and they have decided to "silence" their guns. Earlier in the morning, military spokesman Brigadier Udaya Nanayakkara had said that Prabhakarn was still alive but completely encircled by advancing Sri Lankan forces in a tiny jungle area north of Vellamullivaikkal after most of the LTTE's top leaders were found killed. The Army said that its special forces had encircled Prabhakaran, Pottu Amman and Soosoi who were boxed into a 100m x 100m area. The killing of Prabhakaran came as officials confirmed that more than 220 frontline rebel cadres, including his elder son Charles Anthony, LTTE political head Balasingham Nadesan and LTTE peace Secretariat chief S Pulidevan had been killed in fierce battles in the last 12 hours. The other top LTTE leaders slain include Black Tigers' chief Ramesh, Tigers' police wing chief Ilango and senior leaders Sundaram and Kapil Amman. The body of 24-year-old Anthony, chief of LTTE's air wing, was found during mopping up operations in the last rebel-held territory in the no-fire zone on Monday morning, the Defence Ministry said.
