Supporters of Ugandan opposition leader Kizza Besigye have held a prayer service in a Catholic cathedral to press for his release. On Monday, organizers said church leaders asked to postpone the event after concerns about politics. Attendees stayed inside Lubaga Cathedral anyway to sing hymns and pray. They were led by Besigye’s wife, Winnie Byanyima, who leads UNAIDS. Besigye has spent more than a year in detention without trial. Authorities charge him with treason, which carries the death penalty. His supporters say his health is failing and he needs a doctor of his choice.
