Paris riot police have cleared out students seeking to occupy the Sorbonne university in Paris, as part of a season of protests against President Emmanuel Macron’s reforms.

The university announced its iconic Left Bank site is closed Friday for security reasons after the Thursday night police operation. While about 200 students were evacuated, a few hundred others gathered outside, chanting angrily at police, though the incident ended peacefully.

The site was the epicenter of student protests 50 years ago in May 1968, a pivotal moment in modern French history.

Students at campuses around France are now protesting admissions reforms that they fear threaten access to public university for all high school graduates.
