NEW YORK, Sept. 21 (Xinhua) -- At least two adults were killed and dozens of students were injured after a bus rolled over on a highway in Orange County, U.S. state of New York, on Thursday afternoon, authorities said.

A spokesman for the New York State Police confirmed that two adult women on the bus died and at least five children were in critical condition.

The bus, carrying members of a high school band from Long Island, New York, was heading to a music camp event in Pennsylvania when the accident occurred, according to authorities.

Aerial footage showed a coach-style bus on its side amid trees and brush at the bottom of an embankment. Emergency responders could be seen at the crash scene and a medical helicopter was parked on the highway nearby.

It appeared that "a faulty front tire contributed to the accident," New York Governor Kathy Hochul said at a news conference. An investigation is ongoing.
