One person has died and two others were injured at Old Dominion University in Norfolk, Virginia, in a shooting that the FBI is investigating as an act of terrorism.
The suspect was also killed in the incident on Thursday.
The FBI identified the alleged gunman as Mohamed Bailor Jalloh, a former Virginia National Guard member who had previously been jailed for trying to support the Islamic State group.
Jalloh allegedly opened fire into a classroom and some students were able to subdue and kill him, said Dominique Evans, Special Agent in Charge of the Norfolk FBI field office, at a news conference.
The students "subdued him, and rendered him no longer alive", she said, adding that he was not shot, without providing further details.
