In the past few years, there has been a serious deterioration in the climate for free expression in Bangladesh. Radical Islamist groups have claimed the killings of at least six bloggers, free thinkers, and their publishers since February 2015, and recently, the attacks have widened to include civil society actors, academics, and religious figures with diverse views. Dozens of other dissenting voices have been driven into hiding or exile. Meanwhile, speech is increasingly constrained by a restrictive legal environment, official attempts to undermine independent media, blocks on social media and other communications applications, and a lack of governmental support for the principle of freedom of expression and an unwillingness to provide police protection to those at risk. PEN’s work on Bangladesh has expanded significantly since February 2015, when Avijit Roy, a Bangladeshi-American secularist writer, was murdered while leaving a book fair in Dhaka. Our advocacy centers on persuading the Bangladeshi government to adequately address and stop attacks on free speech, and on the U.S. government and other international actors to support writers and others under threat.
