A large apartment fire sent two Firefighters to the hospital and forced more than a dozen residents to evacuate Wednesday night.

The fire broke out in South Knoxville on Sevier Avenue near the James White Parkway around 8:30.

The Knoxville Fire Department says part of the roof of the building fell on two Firefighters who were hospitalized with non-life threatening injuries.

Firefighters say the fire started in the upper floors of the building, but no cause is known yet.

None of the 14 residents of the apartment building were injured. The Red Cross has offered to take them in.
