THE HAGUE (AP) — The University of Amsterdam canceled classes Tuesday and shut buildings for two days after the latest pro-Palestinian demonstrations over the war in Gaza turned destructive.

Protests continued to simmer at several European universities where students faced off with academic authorities on whether relations with Israel should be broken off or drastically reduced, as the death toll continues to climb during the seven-month Israel-hamas war.

Overall, the protests in Europe have failed to reach the intensity of demonstrations at several U.S. universities.

In the Netherlands, the board at the nearly 400-year old University of Amsterdam issued a statement saying it could not guarantee the safety of anyone on campus after a group of masked agitators barricaded doors and spray painted slogans on the walls.

The mayhem on Monday followed a peaceful walkout of staff and students against the Israel-Hamas war and the university’s response to earlier protests.
