A number of buildings on the University of Minnesota’s Minneapolis campus were evacuated Tuesday because of a gas leak, fire officials said.

A tweet from the university says the Minneapolis Fire Department ordered the evacuation of Williams Arena, Huntington Bank Stadium, McNamara Alumni Center, the Aquatics Center, Recreation Center, Mariucci arena and the Maturi Sports Pavilion.

Fire officials advised people to stay away from the area on the East Bank campus.
