In a move to address escalating protests against Israel on Greek college campuses, authorities have decided to deport nine foreign students from the United Kingdom and European Union member states.

The students, detained after participating in a pro-Palestinian rally at Athens Law School on May 14, are now facing expulsion.

The rally saw 28 people arrested on charges ranging from disturbing public order and damaging property to trespassing and possessing prohibited items such as weapons or flares.

Of those detained, nine non-Greek nationals were deemed “unwanted aliens” who pose threats to public safety and national security, prompting deportation proceedings.
