Sri Lanka remained a highly restrictive and dangerous nation for the press. Critical or opposition journalists continued to face a climate of intense intimidation. More than 20 journalists have gone into exile in the last five years, one of the highest rates in the world. Work-related murders have declined since 2009, but the slayings of nine journalists have gone unsolved over the last decade, one of the worst records of impunity in the world. The government moved aggressively to obstruct the flow of information. In July, the Ministry of Media and Information blocked efforts to introduce freedom of information legislation before parliament, saying national security would be threatened if citizens were given access to public documents. The government had barred previous right-to-information efforts, including one in 2011. In June, police raided the offices of two opposition news websites, arresting staff members and confiscating equipment. At least five other critical websites were blocked. And in March, the authorities told all news organizations they must obtain prior official approval before issuing any text or SMS news alerts that carried information about the military or police.
