A tour bus carrying 37 people from Washington D.C. to Niagara Falls crashed on Sunday, leaving at least two dead and as many as three severely injured, authorities said.  The crash occurred on a western New York state highway late Sunday evening.

A spokeswoman for the area's trauma center said that four people had arrived there and that two more were expected.

The identities of the victims were not released but State Police Troop E spokesman Mark O'Donnell indicated that it appeared that most or all of the bus passengers may have been from India.

The trooper, speaking from the police barracks in Steuben County after returning from the crash scene, said initial reports indicated that the bus may have gone out of control after a tire blew out.

The tour bus was headed northbound on Interstate 390 in the Avoca area when the single-vehicle crashed occurred at about 4:15 p.m.

O'Donnell confirmed that the bus, owned by Bedore Tours of North Tonawanda near Buffalo, left Washington D.C. on Sunday morning and stopped for lunch in Pennsylvania.  The company's website says that it has been providing tours to Niagara Falls since 1950.
