In Uganda the country’s leading opposition politician — Kiiza Besigye — has been arrested. The government has charged him with treason and rape. Besigye had lived in exile in South Africa for four years but returned to Uganda three weeks ago to run in the country’s upcoming election. If found guilty, Besigye could face the death penalty. Thousands of supporters of Besigye’s filled the streets Monday in protest. Police responded by firing teargas at the demonstrators.
