Tunis - Barbed wire and rows of armed soldiers are separating rival demonstrators at the trial of the controversial owner of a private television station in Tunis.
Owner of Nessma TV station Nabil Karoui is being sued by Islamist lawyers for "attacking the sacred and disturbing public order" after his station aired the award winning animated film Persepolis in October.
The film contains a scene showing a character representing God, which is considered sacrilege in Islam.
At the last session of the trial in January, hardline Islamists demonstrated outside the courthouse and attacked some of the people attending.
On Thursday, there was a heavy military presence at the court with soldiers and barbed wire separating rival demonstrations.
Liberal demonstrators said the trial was an attack on freedom of expression.
