WASHINGTON -- Students were evacuated campus-wide after an electrical fire at American University just before 8 a.m.

According to authorities, firefighters responded to a box alarm at 4400 Massachusetts Avenue, NW. When they arrived, they discovered an underground electrical transformer burning.

No injuries have been reported.

American University Police asked all students on campus to evacuate and gather on the main quad. Later, they began allowing students to return to some buildings.

Fire officials says the fire happened at one dormitory but three nearby dorm buildings were evacuated as a precaution.
