Two Turkish lawyers have asked prosecutors to indict the assistant director and the producer of the anti-Islam film that has sparked deadly protests around the Muslim world, they said Thursday.

Ozlem Gezeker and Ozgur Meric Turan, registered lawyers in Ankara, have asked prosecutors in the Turkish capital to try the creators of the controversial film "Innocence of Muslims" under Turkish law for "attacking moral values" and "religious hatred", they said in a statement.

The lawyers said if the film's creators set foot in Turkey they should be punished under the Turkish penal code, which provides for a sentence of up to three years for the alleged crimes.

The low-budget film, which was produced by US-based extremist Christians and depicts the Prophet Mohammed as a thuggish womaniser, has so far not caused violent protests in majority-Muslim Turkey, but Islamist organisations have called for demonstrations after Friday prayers.
