Censorship of Facebook

Several countries have interfered with or banned access to the social networking website Facebook, includingChina,Iran, and North Korea. Use of the website has also been restricted in other ways in other countries. As of May 2016, the only countries to ban access around the clock to the social networking site are China, Iran, and North Korea. However, since the vast majority of North Korean residents do not have access to the internet, in reality China and Iran are the only countries where access to Facebook is actively restricted in a wholesale manner.

Bangladesh banned Facebook for a short period of time among the four nations including Iran, China & North Korea. The Awami League-led government of Bangladesh announced a countrywide ban on Facebook and other social network websites. Prime Minister Sheikh Hasina proposed the establishment of an Internet monitoring committee with the help of Bangladesh's intelligence services. Previously the government has been blocking websites. Right-wing political parties and groups in Bangladesh have been protesting bloggers and others they consider "blasphemous"; at the time of the proposal, eight secularists had been murdered by extremists in the country, including atheist blogger Ahmed Rajib Haider, who was fatally stabbed in February 2013. National riots over country's war crimes trials have killed 56 people between 19 January 2013 and 2 March 2013.

On 18 November 2015, the same Awami League government banned Facebook again on the eve of the final judgement of Bangladesh Jamaat-e-Islami leader Ali Ahsan Muhammad Mujahid and Bangladesh Nationalist Party leader Salauddin Kader Chowdhury. Both the politicians and previous minister have been issued a death sentence by the War Criminals Tribunal and the review board of the Supreme Court of Bangladesh has finally given their judgement in favour of the previously given one.
