One person has died after a helicopter crashed on to the roof of a Manhattan skyscraper before bursting into flames.
The chopper was said to be "flying erratically" before it crash landed on the AXA Equitable Center building on 7th Avenue, which is close to the Empire State Building and Times Square.
It had also been flying within restricted airspace, where aircraft are forbidden from flying below 3,000 feet (914 metres) within a one-mile radius of Trump Tower.
The tower is just a few blocks from the site of the crash.
New York Mayor Bill De Blasio said there was no indication that the crash was an "act of terrorism", and said the person who died was believed to be the pilot.
No other injuries were reported.
New York Governor Andrew Cuomo arrived at the scene shortly after the incident, and says everyone in the high-rise is ok.
Donald Trump also tweeted to confirm he had been briefed, praising the "phenomenal job" carried out by emergency services, and those still at the scene.
He said: "The Trump administration stands ready should you need anything at all."
