A mass shooting overnight at a club in Brooklyn left three people dead and another nine wounded, police officials and the mayor said Sunday morning.

Two of the three people killed in a bar shooting in the New York City borough of Brooklyn were among the four shooters who opened fire inside the building, the city's police commissioner said Monday.

New York City was shaken by a mass shooting in which 11 people were hit, of whom three have died, at a restaurant-cum-lounge

The Brooklyn hookah lounge where three people were killed and nine others wounded early Sunday was right at the scene of another shooting less than a year ago.

What began as a dispute inside the packed nightclub escalated when multiple gunmen opened fire, unleashing chaos before fleeing into the streets.
