A firefighter was hurt while battling a blaze in Jersey City Sunday morning.

The three-alarm fire began just before 8 a.m. on Myrtle Avenue, and amid the flames one firefighter fell about 10 feet.

"He wasn't sure what happened. He said one minute he was on the second floor, the next minute he knew he was on the first floor," says Jersey City Fire Department Chief Steven McGill. 

McGill says he was with the injured firefighter during an X-ray, where doctors told him they don't believe he has any broken bones.

The fire eventually bridged the alleyway to the home next door, causing fire damage there as well.

Everyone in the affected buildings made it out uninjured, but now 12 to 15 people are temporarily without a home.

The cause of the fire is under investigation.
