Prof Mohammed Dajani, head of the American Studies Department and director of the library at Al Quds University, was denounced as a "traitor" and "collaborator" by some of his colleagues, students and members of the public, after he organised the trip to the site of the Nazi concentration camp in Poland. It was announced that Prof Dajani was also "fired" from the university staff union, despite never having joined the organisation in the first place.
