The opposition groups said they would boycott both parliamentary elections planned for Monday, and a presidential vote set for July 15. Representatives of the country’s oppositions signed a letter handed to the election commission, saying they would not take part in the elections until their conditions were met. Opposition conditions for fair elections includes "disarmament of the Imbonerakure militia, the security of the electoral process and political leaders and society, and the reopening of the independent media, the return of refugees".
