At a remembrance event held at Jaffna University last week, students gathered to pay tribute to members of the Malayaga Tamil community who had fought for the rights of their people.
Students laid flowers and lit candles before a portrait that showed the scarred hands of a tea plantation worker.
The Malayaga Tamil community remain some of the most impoverished on the whole island.
Last year, a Guardian investigation revealed that workers in tea plantations, which remain staffed by Malayaga Tamils, were unable to pay for food and were living in unsanitary conditions.
