Political prisoners inside Yangon’s notorious Insein Prison were violently beaten by prison staff earlier this week, in what rights groups describe as systematic abuse targeting anti-regime detainees across Myanmar. Around 30 political prisoners returning from a football match inside the prison compound were attacked by Aung Kyaw Sint, head of Dormitory No. 1, on Sunday, according to sources with knowledge of the incident. They report that he bludgeoned them with a baton without provocation.
