Internet blogger Abdel Karim Suleiman has been sentenced by Egyptian courts to four years in jail for insulting Islam and his country's president, all on a forum designed to be open and free. Suleiman is the first person to stand trial in the country for writings published on a blog, but he joins scores of other "cyber dissidents" across the world imprisoned for blogging. China is the world's biggest cyber prison according to human rights groups, where fifty people are in jail. Vietnam is south east Asia's biggest offender, But it is the growth of repression by Middle East governments that is alarming freedom of expression advocates. Syria, Iran, Tunisia and Libya have all jailed bloggers.
