Police in the United States have arrested over 2,000 students, in what is considered the most unique protest in recent decades.
Protesters involved in mass protests oppose Israel's war on Gaza. CNN reports that a police officer accidentally fired his gun inside Columbia University, but there were no casualties.
Tented camps of protesters have been set up on all university campuses. They call on universities to stop doing business with Israel or companies they say support the war in Gaza.
Israel has branded the protests as anti-Semitic, while Israel's critics say it uses those charges to silence domestic opposition.
Meanwhile, President Joe Biden defended the students' right to peaceful protest, but condemned the unrest of recent days.
The Democratic president "broke days" of silence on the protests with his comments, which followed mounting criticism from Republicans who have sought to turn the scenes of unrest into an election coup.
By focusing on a message of law and order while defending the right to free speech, Biden is seeking middle ground on a contentious issue in the middle of his re-election campaign.
He largely avoided the protesters' demands, which included an end to US support for Israeli military operations.
Asked if the demonstrations would prompt him to consider a change of course, Biden responded with a simple "no."
Biden said he "didn't want the National Guard to be stationed on campuses."
Some Republicans have called for sending in troops, an idea with a rocky history. Four students were shot and killed at Kent State University by members of the Ohio National Guard during protests against the Vietnam War in 1970.
Tensions on college campuses have been high for days as protesters refuse to vacate the camps and administrators turn to police to clear them by force, leading to clashes that have drawn widespread attention.
Biden said he opposes attempts to use the situation to "score political points," calling the situation a "moment of clarity."
Biden will make his visit to a college campus on May 19, when he is scheduled to deliver the commencement address at Morehouse University in Atlanta.
More than 34,000 people have died in Gaza after Israel's attacks. The US is the main supplier of military aid to Israel and has shielded the country from critical United Nations votes.
