'Shots' reports spark chaos at New York's JFK Airport

Reports of shots fired at New York's John F Kennedy International Airport caused evacuations, grounded flights and frightening moments for fliers before the reports were later determined to be unfounded.

"At this time, no firearm, rounds or shell casings or other evidence of shots fired has been found," said Joe Pentangelo, a spokesman for the Port Authority of New York and New Jersey Police Department.
