Unidentified gunmen shot dead a Tamil journalist in northern Sri Lanka in the latest in a string of attacks against media personnel, a rights group said on Friday.
Subash Chandraboas, 32, editor of the Tamil monthly Nilam, was gunned down late Monday at his residence in Vavuniya, 260 kilometres north of here, the Free Media Movement (FMM) said.
Chandraboas also freelanced for other publications.
The FMM, which consists of journalists and rights activists, said it was "appalled by this killing."
"Although the reason for killing him is not clear, the FMM fears that this could be another attack on journalists and media personnel working in north and east," where fighting is raging between the government and Tamil Tiger rebels, the statement said.
The report on the killing comes after an editor from a national daily said she received a death threat from Sri Lanka's defence secretary Gotabhaya Rajapaksa, a charge denied by him.
Media organisations have described Sri Lanka as the most dangerous place on earth for journalists after Iraq, and rights groups say that critics of government policy are treated as traitors and enemies of the state.
Although there is no formal censorship imposed, Sri Lankan authorities prevent journalists from travelling to areas held by rebels, who are waging a separatist conflict that has killed more than 60,000 people since 1972.
