At least two people were killed and eight others critically injured in a Saturday afternoon shooting at Brown University in Providence, Rhode Island.
The shooter remains at large as of 6:50 p.m. EST, despite initial reports that a suspect had been taken into custody.
Providence Mayor Brett Smiley said the shooting occurred at the Barus & Holley building, which houses the university’s engineering and physics departments.
“The unthinkable has happened,” Rhode Island Gov. Daniel McKee said at a news conference.
US President Donald Trump told reporters he's been fully briefed about the deadly shooting.
"What a terrible thing it is. And all we can do right now is pray for the victims," he said.
A text message sent earlier by school officials warned students to "lock doors, silence phones and stay hidden until further notice," Fox News reported.
"Remember: RUN, if you are in the affected location, evacuate safely if you can; HIDE, if evacuation is not possible, take cover; FIGHT, as a last resort, take action to protect yourself," school officials wrote in the alert. "Stay tuned for further safety information."
