Multiple people have died after a tour bus crashed on the New York State Thruway in western New York, according to New York State Police.

Police said the group was returning from Niagara Falls on the US-Canada border to New York City when witnesses saw the vehicle lose control and turn over. Most of the victims are from India, China and the Philippines, according to police.

New York Governor Kathy Hochul said local officials "are working to rescue and provide assistance to everyone involved".

Ambulances and medical helicopters were sent to the crash site, near the town of Pembroke, 30 miles (48km) east of the city of Buffalo.

At least one child has been killed, said New York State Police spokesman James O'Callaghan.
