At least two people have been killed and eight others critically injured in a shooting on the campus of Brown University in Providence, Rhode Island, officials have said.
Final exams were taking place in the engineering building on Saturday afternoon when a shooter opened fire, Brown University provost Frank Doyle said.
Police said the suspect – described as a male dressed in black – left the building on foot and is still at large.
Officers searched the buildings of the Ivy League campus and sifted through trash cans for several hours after the shooting erupted.
Providence mayor Brett Smiley said a “shelter-in-place” was in effect for the area and urged people living near the campus to stay inside and not to return home until it is lifted.
“We have all available resources” to find the suspect, he said at a news conference.
Mr Smiley said a person who was initially thought to be involved in the shooting was detained, but was later determined to have no involvement.
He said the eight wounded people were in critical but stable condition, but declined to say whether the victims were students.
Mr Smiley asked for prayers for the families of the victims, noting the coming Christmas holiday.
“It’s going to be a difficult rest of the day, difficult days and months ahead as this community heals,” he said.
Rhode Island governor Dan McKee said: “The unthinkable has happened.”
The shooting was reported near the Barus & Holley building, a seven-storey structure that houses the School of Engineering and Physics Department, according to the Ivy League university’s website.
It includes 117 laboratories, 150 offices and 15 classrooms.
