Protesters have formed a human chain outside Columbia University's Hamilton Hall

Taking over Hamilton Hall , Columbia students unfurl a banner that reads "Hind's Hall," in reference to Hind Rajab, a six-year-old girl killed by Israeli forces.

Hundreds of students cheer as the banner is revealed, erupting into chants to "Free Palestine."
