According to NBC New York broadcaster, the fire at Rockland County broke out overnight into Tuesday and firefighters have so far failed to localize the blaze.
One person evacuated from the 200-bed facility died at a hospital, while about 20 residents were rescued. It is still unclear how many people were inside the building when the fire broke out.
Two firefighters were reportedly injured while trying to extinguish the fire. The raging fire also caused a part of the building to collapse.
