China and Iran have also restricted Twitter from operating.
Nigeria blocked access to Twitter in the country indefinitely on Friday evening, shortly after the company deleted a tweet by the country’s president, adding Africa’s most populous country to a short list of nations that have barred their citizens from using Twitter: Nigeria’s faceoff with Twitter started earlier this week, when President Muhammadu Buhari threatened to deal with separatist groups accused of violence “in the language they understand,” a reference to the country’s brutal civil war more than 50 years ago.
