An Air Canada Express regional jet collided with a ground vehicle upon landing at New York's LaGuardia Airport on Monday evening, according to flight-tracking website Flightradar24, in an incident that closed the airport.

The CRJ-900 plane, which was coming from Montreal, struck ​the vehicle at a speed of about 24 miles ​per hour (39 kph), Flightradar24 said. The jet was ⁠operated by Jazz Aviation, Air Canada's regional partner.

The U.S. ​Federal Aviation Administration (FAA) issued a ground stop for all planes ​at the airport until 0530 GMT, according to a notice from the regulator.

The FAA notice stated that the airport halt was due to an emergency and that there was a high probability of an extension, without specifying any details.

LaGuardia's website showed arriving ‌planes ⁠had been diverted to other airports or returned to their point of origin.

In a separate notice to airmen, the FAA said the airport could be shut down until 1800 GMT.

Unverified footage on ​social media ⁠showed damage to the nose of the plane, as it tilted upward. Reuters could not ​immediately verify the footage.

The New York Fire Department ​, in ⁠a statement, said that it was responding to a reported incident involving a plane and a vehicle on the runway ⁠at ​LaGuardia Airport, but did not provide ​further details.

Air Canada and the FAA did not immediately respond to requests for ​comment.
