A three-alarm fire tore through a row of homes Monday morning in Shamokin, displacing multiple families and sending at least one person to the hospital with serious injuries.

Emergency crews were called to 1019 North Franklin Street around 8:30 a.m. where they found heavy flames rapidly spreading through attached row houses. Before arriving on scene command reported the incident was visible from multiple blocks out and immediately requested a second alarm. The fire intensified quickly, prompting a third alarm for additional manpower and drawing firefighters from several neighboring departments.

Officials said the blaze damaged at least four homes and forced approximately a dozen residents from their properties. One victim suffered burns and was airlifted to a regional burn center for treatment. 

Firefighters worked for about an hour to bring the main body of the fire under control, though crews remained on scene for several hours afterward to extinguish hot spots and investigation.

The American Red Cross is assisting several displaced residents.

Authorities have not yet determined the cause of the fire.
