Supporters of Mam Sonando, owner of a local independent radio station and land rights campaigner, take part in a protest demanding his release in front of the Appeal Court in Phnom Penh March 5, 2013. Sonando was at the court to hear his appeal against his sentencing to 20 years in prison in 2012 for leading an anti-state rebellion, a verdict condemned by activists as a further crackdown on human rights. The sign reads, "Release Mam Sonando." REUTERS/Samrang Pring
