It looked like a scene from a movie or video game, Rob Glinski said. The large white bus in front of him on the New York State Thruway had been going over 70 miles an hour when it began swerving between lanes.

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 possibility of mechanical failure and impairment or intoxication of the driver as causes of the crash have been ruled out. The Indian national was identified as Shankar Kumar Jha, 65, from Bihar.
