A man was killed and two others hurt during a shoot-out between rival groups in an East Harlem housing development early Saturday, cops said.

The 19-year-old victim, and two other men, 21 and 25, were fighting with another group at the Carver Houses on East 104th Street near Madison Avenue when someone opened fire on them, according to police.

The youngest victim, who was blasted in the torso, was rushed to Mount Sinai Hospital, where he was pronounced dead.

The 21-year-old victim, who was shot in the foot, and the oldest victim, who was grazed in the torso, were taken to the same hospital in stable condition.

No arrests had been made by Saturday afternoon.
