Journalist one of many unanswered disappearances in Sri Lanka

It is over five hundred days since a website journalist and cartoonist in Sri Lanka, Prageeth Ekneligoda, disappeared after apparently being abducted.

No information on his fate has emerged.

He is just one among many Sri Lankans who have vanished and whose fate remains unclear.

The UN's working group on disappearances said it has been waiting more than four years for the government to respond to its request to visit Sri Lanka.
