Twenty-one people were killed and dozens more injured when a small cruise ship capsized in an upstate New York lake Sunday afternoon.

The glass-enclosed Ethan Allan was carrying 49 passengers and crew on a Lake George senior citizens' cruise. The seniors were part of a tour group from Canada.

The Warren County Sheriff, Larry Cleveland, said his office is investigating reports that the Ethan Allan capsized when a larger tour boat passed nearby and swamped it.

The accident happened so fast that none of the Ethan Allan's elderly passengers was able to put on a life jacket in time. At least five of the injured were hospitalized.

The owner of the cruiseline that operated the boat said the incident was a tragedy and "very unfortunate."

Lake George is about 320 kilometers north of New York City.
