Human rights have come under increasing pressure and rising tension between the government and its critics. Hundreds of people have been arrested or imprisoned for participating in protests. In August-September 2010, the authorities swooped on 23 opposition political activists, detaining them incommunicado for two weeks during which some allege they were tortured. Meanwhile, the authorities have curtailed freedom of expression, closing critical websites and banning opposition publications. Years of progress and achievement could be erased unless urgent measures are taken to reverse the downward trend.
