The pilot and co-pilot of an Air Canada Express regional jet were killed after it collided with a fire engine while landing at New York's LaGuardia airport late last night, in an incident that closed the airport, authorities and US media said.
NBC News, which reported the deaths, said dozens of others were injured in the incident.
The news channel said that the fire engine was manned by police officers, citing sources.
It had earlier said a sergeant and an officer had broken limbs and were in stable condition at a hospital.
The Air Canada Express CRJ-900 plane, operated by its partner Jazz Aviation, was carrying 72 passengers and four crew members from Montreal, based on a preliminary passenger list that remained subject to confirmation.
Jazz is owned by Chorus Aviation.
The CRJ-900 plane struck the vehicle at a speed of about 39km/h, said Flightradar24, which last recorded data at 11.37pm local time in New York (3.37am Irish time).
Photos taken after the incident showed visible damage to the nose of the plane, which was tilted upward.
Authorities and emergency agencies did not offer any immediate comments on injuries.
The US Federal Aviation Administration (FAA) said the airport was expected to remain shut until 2pm local time this afternoon.
Flightradar24 said 18 flights had been diverted to other airports, mostly in the New York area, or returned to their point of origin.
Air Canada referred Reuters to Jazz's statement and said it was aware of the incident. The National Transportation Safety Board and the FAA did not immediately respond to requests for comment.
The Port Authority of New York and New Jersey said the firefighting vehicle was responding to a separate incident when it was struck by the aircraft at the airport's Runway 4.
New York City's emergency notification system said people could expect cancellations, road closures, traffic delays and emergency personnel near the airport.
LaGuardia served over 30 million annual passengers in 2025, according to the Port Authority of New York and New Jersey, and a wide range of US airlines operate at the airport.
