Pro-Palestine protesters briefly disrupted a commencement ceremony at the University of Michigan on Saturday while demonstrators faced off with police at the University of Virginia as US colleges braced for more turmoil during graduation festivities, Reuters reports.

Videos shared on social media showed dozens of students wearing the traditional keffiyeh headdress and graduation caps and waving Palestinian flags as they walked down the centre aisle of Michigan Stadium in Ann Arbor, among cheers and boos from a crowd of thousands.

The ceremony continued and campus police escorted the protesters toward the back of the stadium, but no arrests were made, according to Colleen Mastony, a spokesperson for the university.

“Peaceful protests like this have taken place at U-M commencement ceremonies for decades,” Mastony said in a statement. “The university supports free speech and expression, and university leaders are pleased that today’s commencement was such a proud and triumphant moment.”

Police have so far arrested over 2,000 protesters at colleges around the country.
