Nigeria will arrest Twitter users after ban

Nigeria will arrest and prosecute people in the country who use Twitter after the government banned the app on Friday in retaliation for the social media company temporarily freezing Nigerian President Muhammadu Buhari's account, according to CNN.

Why it matters: Twitter has been extremely popular in Nigeria, the most populous country in Africa. The app and other social media platforms are routinely used by citizens around the world to voice their dissent or concerns to their governments.
