Agroup of pro-Palestine students invaded a lecture being held at University of Pisa's political science department on Tuesday, forcing the lesson to be abandoned.

The teacher who was giving the lesson, Rino Casella, a professor of comparative law, went to hospital to be treated for bruises he suffered while trying to stop the lecture hall being occupied and then went to a police station to press charges, sources said.

The 'Studenti per la Palestina' movement had called Casella a "Zionist professor" on social media.

Higher Education Minister Anna Maria Bernini said she had called Cascella, University Rector Riccardo Zucchi and Pisa Prefect Maria Luisa D'Alessandro after the raid.

"Universities are not no-fly zones where interrupting lectures or assaulting professors is allowed," Bernini said.
