A helicopter has crashed into New York City's East River, killing at least two people.
The helicopter, a model used by tourist companies, went down near Gracie Mansion, the mayoral residence. A small armada of rescue boats searched for survivors.
Video posted on Twitter shows a red helicopter land hard in the water and then flip on its side as its rotors beat the water.
News stations showed video of rescue boats at the spot where the helicopter crashed.
It was not immediately known how many people were aboard the aircraft.
