Two people are in critical condition after a fire at a home in Burlington County, New Jersey, officials said Wednesday. First responders said neighbors jumped into action to rescue some of the people inside the house.

Burlington Township police were called to a home on Laclede Drive just before 9 a.m. Wednesday.

Police said an 89-year-old man and 90-year-old woman were rescued from the home. They were airlifted to a Philadelphia hospital, where they are in critical condition in the burn center.

Albert Oliver lived across the street from the home. He was running late for work Wednesday morning when he looked outside and saw smoke billowing from his neighbor's house.

"You never think it's going to happen to you," Oliver said. "That's what I thought. And when you see it, it's like, 'Wow.' Like, I couldn't believe it was happening."

Oliver said he ran into the home and helped get a man out of the house.

"I started hollering his name. Nobody responded," Oliver said. "The smoke was too thick to where I couldn't breathe, so I had to come back out. And when I went back in, he emerged from the kitchen. Coming from the kitchen, that's when I grabbed him."

Fire investigators believe the blaze originated from the back of the home, but it remains under investigation.

Two police officers were taken to the hospital with smoke inhalation and were later released, the department said.
