It's still appears to be very much an active scene here at the site of the incident. We are told law enforcement will hold a press conference soon with the latest.

We just saw a team of New York Fire Department rescue workers dock here at this pier in their wet suits.

It's still raining, so that could potentially have hampered the operation, though the authorities wouldn't comment.

I am near the scene of the New York helicopter crash, where rescue teams are gathered along Pier 40.

A helicopter is hovering above us as it begins to rain. Scores of lights are flashing from fire and police vehicles as some onlookers gather.

The NYPD says they are still in the very preliminary stages of its response and will provide more details a bit later on.

The BBC's US news partner CBS is now reporting that least six people are dead after a helicopter crashed into the Hudson River.

There were at least three children and three adults on board, CBS says, clarifying its earlier reporting that there were five people on board.

New York City Mayor Eric Adams has tweeted about the crash, calling it "heartbreaking and tragic".

He goes on to say the fire and police departments in New York are assisting first responders in New Jersey who are also responding. He advised local residents to avoid the area.

The Federal Aviation Administration (FAA) says in a statement that the crashed helicopter is a Bell 206 - a type of two-bladed helicopter. The agency says it cannot confirm how many people were on board the flight, though as we've reported, our US partner CBS News says there were at least five people were on board.

The FAA says it will conduct an investigation led by the National Transportation Safety Board, which will also provide further updates.

They add that at least two people have been pulled from the water, with sources that spoke to CBS saying one was a child.

A Hudson County official says the other is the pilot. We don't have information yet about their condition.

As we reported a short while ago, at least one person has been confirmed dead.

Video footage posted to social media appears to show the helicopter falling out of the sky upside down and splashing down in the Hudson River.

Pedestrians are then seen rushing over to get a glimpse.

The BBC has not independently verified this footage.

According to flight tracking website FlightRadar, it appears the helicopter involved in the crash was in the air for 15 minutes.

The tracking site adds in a post on X, , externalalongside a graphic of the flight path, the helicopter appears to have taken off from the New York Downtown Manhattan Heliport.

The aircraft seems to be a Bell 206L-4 LongRanger IV which has a private owner, the post adds. This is a single engine turbine helicopter that can typically accommodate seven passengers.

I'm currently at the top of the World Trade Center, and what’s happening in the river has caught a lot of tourists' attention here, most people have come to one side of the tower to look down onto the Hudson River.

There are about a dozen various boats all surrounding one of the piers on the New Jersey side of the River Hudson, while on the Manhattan side directly across there are swarms of flashing lights from emergency service vehicles.

And now weather conditions are starting to worsen with a small bit of snow.

We are getting a lot of information very rapidly about this developing situation. Here's what we know so far:

• At least one person is dead, after a helicopter crashed into New York's Hudson River around 15:15 EDT (20:15 BST)
• At least two people have been pulled from the water, but their condition is unknown, the New York Police Department said
• A large number of emergency services are on scene, both on boats and on land
• The crash occurred near the shore, next to Pier 40, across the river from New Jersey
• We still don't know how many were on board in total

The part of the river where the helicopter crashed is near the West Side of Manhattan. The surrounding area is a neighbourhood called the West Village, a trendy area known for its shops and dining, also near the main campus of New York University.

Also in the vicinity is the Holland Tunnel, one of the main modes of travel between New York City and New Jersey.

One person has died following the helicopter crash, CBS News, the BBC's US news partner says.

The New York Police Department told CBS that at least two people have been pulled from the water, but their condition is unknown.
