Anti-Israel protesters at Columbia University have burned their own diplomas in an effort to rage against the institution for bowing down to the Trump administration.

Rowdy demonstrators gathered outside the graduation ceremony on Wednesday, raucously chanting 'Free Palestine', wearing keffiyehs and holding a Palestinian flag with 'Free Mahmoud Khalil' written on it.

Khalil, a student at Columbia from Syria who was in the United States on a green card, is in custody awaiting deportation after he was arrested back in March accused of organizing pro-Palestinian rallies on campus.

He served as a spokesman for the Columbia University Apartheid Divest group, or CUAD, on campus during the disruptive encampments and protests which gripped Columbia last year.

Extraordinary photographs from the protest captured students setting fire to their own diplomas after pouring years of effort and thousands of dollars into achieving the certificate.
