In a surprise move, Hailemariam Desalegn, the Ethiopian prime minister, has announced the release of political prisoners and the closure of a notorious detention centre, allegedly used as a torture chamber. He said the move was designed to allow political dialogue. It is still unclear exactly who will be released or when it will happen. Ethiopia is accused by rights groups of using mass arrests to stifle opposition. Amnesty International welcomed Mr Hailemariam's announcement, saying it could signal ‘the end of an era of bloody repression in Ethiopia’.
