After spending the morning taking in the breathtaking sights at Niagara Falls, a group of tourists boarded a bus to return to New York City, not knowing about an hour later, their bus would be lying on its side in the ditch off the New York State Thruway.

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.

A tour bus with more than 50 passengers lost control and rolled over on the New York State Thruway near Pembroke, killing five people, police said.
