NEW YORK - Two children were killed and two more were left in critical condition Friday after a house fire in Staten Island, according to officials.
The fire broke out just before 10:20 a.m. inside a house located on Van Duzer Street.
The FDNY said the building's entire second floor was engulfed in flames.
"We found the victims inside, all unconscious and needing to be removed," said FDNY Chief of Department Jack Hodgens. "We quickly took them to the street and started to perform CPR on all of the victims."
Officials have confirmed with FOX 5 New York that a 5-year-old girl and 6-year-old girl were killed.
Authorities are still working to identify the cause of the fire, but believe that there was no adults home at the time.
A firefighter also suffered a minor injury fighting the fire.
Around 60 firefighters responded to the fire, which was deemed under control at 11:17 a.m.
