Tunis: Tunisian officials say police have arrested around 30 Islamist demonstrators set on attacking the offices of a television channel that had shown the award-winning film Persepolis.

Interior Ministry spokesman Hichem Meddeb says police blocked the attackers before they could reach the offices of the Nessma private television channel in the centre of Tunis.

The head of Nessma, Nabil Karoui, said on radio Mosaique FM that the attackers were angered by the channel's recent showing of Persepolis, Marjane Satrapi's moving and humorous adaptation of her graphic novels about growing up during and after Iran's 1979 Islamic Revolution. He said they consider it hostile to their religious convictions. The film won the jury prize at the 2007 Cannes Film Festival.
