NEW YORK, Oct. 2 (Xinhuanet) -- A tour boat carrying 47 people overturned Sunday on a lake in upstate New York, killing 20 people, AP reported.

    The tour boat was carrying a tour group from Canada, AP reported, quoting Warren County Sheriff Larry Cleveland.

    The vessel capsized when another tour boat passed near it and swamped it, the report said.

    The 40-foot (12-meter), glass-enclosed tour boat flipped around 4 p.m. (2000 GMT) on Lake George about 50 miles (80 kilometers) north of Albany in the Adirondack Mountains.

    Rescuers rushed to the scene and investigations are underway. Enditem
