Justice has been sought for five Tamil youth killed in Trincomalee 12 years ago.
Amnesty International said in a twitter post that it was pushing for justice for the victims.
The human rights group said that the security forces had been accused of being involved in the killing and the killers have not yet been prosecuted.
The five Tamil students were allegedly summarily executed by the Special Task Force, whilst they spent an afternoon on the beach in Trincomalee on 2nd January 2006.
The case – known as the ‘Trinco 5′ – remains one of the highest profile killings in Sri Lanka to receive international attention, listed in 2014 by the then UN High Commissioner for Human Rights’ report on Sri Lanka as one of four ‘emblematic cases’ of the Government’s failure to ensure accountability.
The five slain students, who were all 20-years-old when killed, are Manoharan Ragihar, Yogarajah Hemachchandra, Logitharajah Rohan, Thangathurai Sivanantha and Shanmugarajah Gajendran.
