Three people were killed and another seriously injured by a gunman who was shot dead by police at a United States university on Wednesday (Dec 6).

The incident at the University of Nevada, Las Vegas, a short distance from the gambling hub's tourist-packed Las Vegas Strip, was the latest in the United States, where gun violence is a part of the fabric of daily life.

"Three of the victims are confirmed deceased," Las Vegas Sheriff Kevin McMahill told a press conference.

He said a fourth victim had been critically injured by the shooting but that condition later upgraded to stable.

The identity of the shooter was not immediately released, but CNN and the Los Angeles Times, quoting law enforcement sources, said he was a 67-year-old career college professor with links to schools in Georgia and North Carolina. But it was not clear what affiliation he had with the Nevada university where the shooting took place.

US President Joe Biden in a statement decried the latest "horrific act of gun violence" to terrorise a college campus.
