A gunman opened fire at Old Dominion University in Norfolk, Virginia on Thursday, injuring two people before the shooter was killed, according to university officials.

The shooting occurred in Constant Hall, which houses the university's business school. Two people were injured in the incident and transported to a hospital for treatment. The condition of the victims was not immediately disclosed.

It was not immediately clear how the gunman died or what circumstances led to the shooting. University officials confirmed the suspect was deceased but provided no additional details about the shooter's identity or motive.

Old Dominion University canceled all classes and suspended operations on its main campus for the remainder of Thursday. The university urged people to avoid the area in and around Constant Hall while emergency officials continued their response.

The federal Bureau of Alcohol, Tobacco, Firearms and Explosives confirmed it had agents on scene supporting the emergency response. Norfolk police described the situation as an "active incident" while responding to the campus.

The incident prompted a campus-wide alert system to notify students and staff of the emergency situation as authorities worked to secure the area.
