Flames leapt out of a house in Yonkers just after midnight Friday.
Eighteen people were taken to the hospital, including 13 firefighters. One firefighter suffered a crushed hand – the most serious injury to a firefighter – from setting up a ladder.
Fire crews prevented flames from spreading to neighboring homes.
Five people who lived in the building suffered minor burns and smoke inhalation.
When fire crews arrived, a man and two teens trapped on the fire escape were about to jump.
Firefighters were able to get them to safety.
The three-alarm fire destroyed the building on Alexander Avenue.
The cause of the fire is under investigation.
