The group 's activities intensified in the second half of 1987 in the wake of the Indo-Sri Lanka Accord . The prospect of Tamil autonomy in the north together with the presence of Indian troops stirred up a wave of Sinhalese nationalism and a sudden growth of anti-government violence . During 1987 a new group emerged that was an offshoot of the JVP — the Patriotic Liberation Organization ( Deshapremi Janatha Viyaparaya — DJV ) led by Saman Piyasiri Fernando or '' Keerthi Vijayabahu '' a person who led the JVP after the death of Rohana Wijeweera . The DJV claimed responsibility for the August 1987 assassination attempts on the president and prime minister . In addition , the group launched a campaign of intimidation against the ruling party , killing more than seventy Members of Parliament between July and November
