The family of Tawfiq Omrane says that he has been told that he must attend a court hearing in Tunis next week.

Mr Omrane was detained on Thursday for allegedly insulting the Tunisian prime minister, Ahmed Hachani in his cartoons.

Mr Hachani was appointed by President Kais Saied, who seized almost all executive powers in Tunisia just over two years ago.

Mr Omrane has been highly critical of the president in his cartoons.

Opposition activists see his detention as the latest attack on free speech.
