Campuses of several universities in the United States have been witnessing massive protests with the students seeking a ceasefire in Israel's war with Hamas. 

More than 550 protesters have been arrested and some universities are witnessing violent clashes between cops and activists.

At the behest of college administrators, police have deployed tasers and tear gas against student protesters at Atlanta's Emory University.

However, the protests have been largely peaceful, activists at the spot told the media.

Student protesters said they are expressing solidarity with Palestinians in Gaza, where the death toll has crossed 34,305, according to the Hamas-run territory's health ministry.

The protesters want universities to cut their investments in everything tied to Israel and weapons that fuel the war in Gaza.

That means funds run by BlackRock, Google as well as Amazon's cloud service, Lockheed Martin and even Airbnb.

Video circulated widely on social media shows two women who identified themselves as professors being detained, with one of them slammed to the ground by one officer as a second officer then pushes her chest and face onto a concrete sidewalk.
