Amnesty International condemned a Thai court's decision to uphold a 10-year sentence against social activist and former magazine editor Somyot Prueksakasemsuk.

A man faces 15 years in jail for posting images on Facebook of Bhumibol's favourite dog in a way that mocked the king, according to the prosecutor. And a cleaning lady is being charged for posting the words see in an exchange on Facebook between her and a political activist that police say had defamatory comments.
