Police intervened to block some 200 protesters outside a Swiss university where French President Emmanuel Macron is due to give a speech on Thursday, Swiss public broadcaster SRF said.
Footage on social media platform X showed officers using what appeared to be pepper spray and restraining members of an advancing crowd carrying pro-Palestinian flags and banners.
The cantonal police service did not immediately respond to a request for comment.
Macron is set to address the University of Lausanne in a speech about the challenges facing Europe alongside Swiss President Alain Berset.
