Two people were injured and two pets died when a condo building in Silver Spring, Maryland, caught fire early Thursday morning.
The fire started at the Grand Bel Manor Condominiums on Bel Pre Road at 4:30 a.m. Thursday.
When firefighters arrived, they found heavy fire in a low-level apartment, fire officials say.
Three buildings were damaged by the flames, displacing more than 100 people.
A resident and a firefighter suffered non-life-threatening injuries, Montgomery County Fire and Rescue Service spokesman Pete Piringer said. Piringer said several people and pets were rescued from the fire, but a dog and a cat did not survive.
Fire officials believe the fire was electrical in nature.
