Names of 2 passengers appear on 'no-fly' terrorist list

(CNN) -- U.S. authorities refused to allow a KLM Royal Dutch Airlines 747 to fly over the United States, officials said Sunday.

Flight 685 from Amsterdam to Mexico City was denied permission to fly south across the Canada-U.S. border on Friday because the names of two passengers aboard were included on a U.S. "no-fly" terrorist watch list, KLM spokesman Bart Koster said.

The flight, carrying 278 passengers, returned to Amsterdam, Koster said.
