Kuwaits top court on Monday upheld a 10-year jail sentence for a Shiite Twitter user for insulting the Prophet Mohammed and his wife and companions. Hamad al-Naqi, 24, was also charged with insulting Saudi Arabia and Bahrain and spreading false news that undermined Kuwaits image abroad, the verdict said. Naqi, a member of Kuwaits Shiite minority, denied the accusations, saying his Twitter account was hacked. Human Rights Watch strongly criticised the sentence and urged authorities to immediately release him after the appeals court confirmed the sentence in October last year.
