The producers of the award-winning, Emmy-nominated documentary No Fire Zone: The Killing Fields of Sri Lanka released a version of the movie in the Sinhalese language at an event in the House of Commons in London.
A press release said the new version was a "direct challenge to the new government over its commitment to a free media".
The event, which coincided with the new Sri Lankan President Maithripala Sirisena's visit to London, was attended by No Fire Zone Director Callum Macrae, Labour MP Siobhain McDonagh and Conservative MP Lee Scott and was also addressed by exiled Sinhalese writer Bashana Abeywardane.
“I welcome President Sirisena’s commitment to freeing the media in Sri Lanka from the censorship and repression of the Rajapaksa years,” Mr Macrae said.
