Six No-Fly Listers Denied Boarding

In the two-day period between last Saturday and Monday, at least six people were denied boarding on international flights traveling to U.S. locations.

Two of the six were stopped at London's Heathrow Airport.

On Saturday, an Egyptian man on the no-fly list was stopped from flying on American Airlines flight 113 from London to Miami.

The next day, Sunday, a Saudi Arabian passenger was stopped from boarding United Airlines flight 929 to Chicago. Officials said the man was sent back to Saudi Arabia by the British.

In two other overseas cases involving people on the no-fly list, a man in Nairobi, Kenya was kept off a flight Sunday that would have connected in Amsterdam to Dallas, and a passenger attempting to fly on American Airlines to Los Angeles was stopped in Saint Maarten before he could board a connecting flight to San Juan, Puerto Rico, according to officials.

Meanwhile, authorities have issued a BOLO for female suicide bombers trained by al Qaeda in Yemen. They may have Western passports and be non-Arab in appearance.

And if the foregoing doesn't make you just a little antsy, there's also news that the Brits have raised their terrorism threat level to "severe," the second-highest level. The change comes as London is preparing to host international meetings on Afghanistan and Yemen.
