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, near Buffalo, according to New York State Police.

The bus, which was carrying 54 people to New York City from Niagara Falls, veered off the New York State Thruway near Buffalo.

State police said the bus lost control, went into the median and turned over into a ditch on the side of the road.
