At least 18 residents were displaced, and one firefighter was injured after a five-alarm fire broke out at a Yonkers apartment building on Tuesday.
Fire officials said they first learned about the fire at 50 Riverdale Ave. around 9:17 a.m. The calls they received reported people trapped inside with smoky conditions.
Yonkers Fire Commissioner William Fitzpatrick said the arriving crews saw several balconies on fire in the back of the building.
"Certain apartments had their windows opened. Fire extended into the apartments and eventually spread to about nine floors," Fitzpatrick said.
Officials said the conditions made multiple units in the building uninhabitable.
Fitzpatrick said in addition to the firefighter, one resident was also hurt.
"Yeah, there was one civilian injury who refused to be transported to the hospital. It's a minor injury. One firefighter injury at this time," Fitzpatrick said.
Officials said the firefighter was transported to the hospital and is now in stable condition.
Mayor Mike Spano thanked all of the first responders for their hard work.
Officials said 500 people live in the building.
The cause of the fire was not immediately known.
