A gunman is dead and two people are hurt after a shooting at Old Dominion University on Thursday morning, the Virginia school said.

ODU said a gunman opened fire in its business school building, injuring two people who were sent to the hospital. It wasn’t immediately clear how the shooter died.

Within about an hour of the shooting, ODU declared that there was no longer a threat at the campus.

The public university in Norfolk canceled classes and suspended all operations on its main campus for the rest of Thursday and urged people to avoid the area in and around Constant Hall while emergency officials continued to work.

The federal Bureau of Alcohol, Tobacco, Firearms and Explosives said on the social platform X that it had agents on scene supporting the response.

Located in coastal Norfolk, Old Dominion University has about 24,000 students, 17,500 of them undergraduates. The school has around 240 degree programs, and is known for its research spending and doctoral programs. Nearly 30% of its students are military-affiliated, according to the university website. The area is also home to Naval Station Norfolk, the largest naval station in the world.
