One person died and four others were injured in a fire at a Queens apartment building early Monday morning, authorities said.

The blaze broke out around 3 a.m. on the fifth floor of a six-story building on Elmhurst Avenue near Forley Street in Elmhurst, an FDNY spokesman said.

When firefighters extinguished the flames, they discovered George Ortega, 50, inside apartment 5L with critical injuries. Two others, a 30-year-old man and a 36-year-old woman, were also inside the apartment.

Photos from the scene show firefighters and medics tending to the victims on stretchers.

EMS rushed all three people to Elmhurst Hospital Center, but Ortega could not be saved, police said. The second male victim is in critical condition and the woman suffered injuries that are considered to be minor, according to an FDNY spokesman.

Two firefighters also suffered minor injuries.

The cause of the fire is under investigation by the FDNY Fire Marshals.
