A tour bus returning from a trip to Niagara Falls overturned in upstate New York on Friday, killing five people and injuring dozens of others, some of whom became trapped or ejected, police said. The deadly crash occurred on Interstate 90 in Pembroke,

State police said most of the passengers on the bus were of Indian, Chinese and Filipino ethnicity, and authorities brought in translators to help with the emergency response.

"Avoid the NYS Thruway eastbound at all costs as a tour bus has rolled over near the Erie and Genesee County lines," Erie County executive Mark Poloncarz said on X. "This is a potential mass casualty incident," he said, adding that the county's emergency and security services are assisting.
