WASHINGTON (AP) — Police began to clear a Pro-Palestinian tent encampment at George Washington University early Wednesday and arrested dozens of protesters, hours after dozens left the site and marched to President Ellen Granberg’s home.

Officials at the university in Washington, D.C., had warned of possible suspensions for students engaging in protest activities on University Yard.

“While the university is committed to protecting students’ rights to free expression, the encampment had evolved into an unlawful activity, with participants in direct violation of multiple university policies and city regulations,” the university said in a statement.

Local media had reported that some protesters were pepper sprayed as police stopped them from entering the encampment and nearly 30 people had been arrested, according to community organizers.
