A Kuwaiti man was sentenced to 10 years in prison on Monday after being convicted of endangering state security as a result of messages he sent on Twitter. The judge found Hamad al-Naqi guilty of insulting the prophet Muhammad and Islam, and insulting the rulers of neighbouring Saudi Arabia and Bahrain. Al-Naqi pleaded innocent at the start of the trial last month, saying his Twitter account had been hacked and he had not posted the messages.
