The band of the Asociación Trabajadores del Estado, the state workers’ union, plays a protest anthem on Jan. 16 during a march in the capital demanding the release of activist Milagro Sala. She was arrested two years ago and has been charged with embezzling state funds and inciting criminal acts. Sala is the leader of Tupac Amaru, an organization that provides housing through government funding. Her arrest has received public outcry from groups such as Human Rights Watch and Amnesty International, as well as from Pope Francis.
