Students at Trinity College Dublin and Lausanne University in Switzerland have staged occupations to protest against Israel’s military offensive in Gaza, joining a wave of demonstrations sweeping US campuses, Reuters reports.

In Dublin, students built an encampment on Friday that forced the university to restrict campus access today and close the Book of Kells exhibition, one of Ireland’s top tourist attractions.

The camp was set up after the students’ union said it had been fined 214,000 euros ($230,000) by the university for losses caused by protests in recent months, not exclusively over Gaza. The protesters were demanding that Trinity cut academic ties with Israel and divest from companies with ties to Israel.

Students’ union president Laszlo Molnarfia posted a photograph of benches piled up at the entrance to the building housing the Book of Kells, an illuminated manuscript created by Celtic monks in about 800 AD.

Trinity College said it had restricted access to students, staff and residents to ensure safety, and that the exhibition would be closed today.
