A man and a woman were killed in a fire that broke out Wednesday on the top floor of a four-story building in Park Slope.

The FDNY says the 911 calls came in around 2 a.m. for the two-alarm fire at 155 Fifth Ave.

Officials say the 22-year-old man and 22-year-old woman were pulled from the building and rushed to New York-Presbyterian Brooklyn Methodist Hospital in critical condition.

Police have identified the victims as Destiny Marmoles and Steven Munoz.

The cause of the fire is under investigation.
