Anonymous telephone threats against commercial airliners on Monday, possibly from the same source, caused a scare involving at least five international flights at airports in New York, New Jersey and Massachusetts.
Authorities said the threats did not appear to be credible. They described searches done on the jets as a precaution. In one instance Monday morning, U.S. military jets escorted an Air France flight into New York City after someone claimed a chemical weapon was aboard the aircraft.
