A Metro-North passenger train has derailed in the Bronx area of New York City with at least four people killed and numerous injured.
Despite earlier reports to the contrary, none of the cars ended up in the water.
The incident happened just after 7am New York time.
The train was headed for Central Station, and crashed near Spuyten Duyvil station in the Bronx.
At least 63 people have been injured, Sky News reported, and 135 firefighters were at the scene.
Five out of seven carriages derailed on what was said to be a dangerous bend, according to US reports.
The train stopped close to the mouth of the Harlem River where it flows into the Hudson, Sky News reported.
Passengers were thrown from the train by the impact, and footage showed divers searching in the nearby water.
FDNY (Fire Department of New York) chief of department Edward Kilduff said three people died as they were thrown from the train, The Guardian reported.
Kilduff added: "The train is pretty beat up. There was substantial damage inside and a lot of personal possessions thrown around.
"We believe we've searched the entire area and we don't have any other victims we're aware of."
President Barack Obama said his thoughts and prayers were with the families of the victims.
