The government's effort to silence critical media has been brutally effective as politically motivated deaths, attacks, and disappearances go uninvestigated and unprosecuted. The sister websites Groundviews and Vikalpa became the last independent news sites based in Sri Lanka, after a series of attacks on Lanka eNews. Arsonists attacked the offices of Lanka eNews in January, and authorities arrested the site's Colombo-based editor Bennet Rupasinghe in March. The site continued to publish from London but was blocked domestically. Authorities have turned the notion of law enforcement on its head, obstructing justice in numerous anti-press attacks. Prime examples are the unsolved 2010 disappearance of cartoonist Prageeth Eknelygoda and the unsolved 2009 murder of prominent editor Lasantha Wickramatunga. Anti-press violence continued in 2011. In July, Gnanasundaram Kuhanathan, news editor of the Tamil-language daily Uthayan, was assaulted in northern Sri Lanka by assailants wielding iron bars. News media access to northern, predominantly Tamil areas remained severely restricted. The government and Tamil secessionists rejected allegations that they committed human rights violations during the long civil war, but independent coverage of the abuses was limited.
