DALLAS (AP) – Nobody has been hurt in a fire near the top of a 12-story research and administrative building at the University of Texas Southwestern Medical Center in Dallas.

UT Southwestern spokesman Jeff Carlton says the fire was contained about an hour after being reported around 8:30 a.m. Thursday.

Carlton says about 100 people were in the new building, where staffers already work but some floors are still under construction, and all were safely evacuated.

Carlton says fire department personnel say the blaze happened between the 12th floor and the roof. Authorities are trying to determine what started the fire.

School officials sent an email to students and staff saying firefighters responded to the blaze, on the north part of the campus, and to stay clear of the area.
