CAIRO — The "suicide belt" proved a fake and the diverted EgyptAir flight landed safely in Cyprus, but an abortive hijacking Tuesday is raising fresh questions about the safety of Egypt's airports, just months after security flaws were blamed for failing to stop a terrorist attack on a Russian airliner that marked the deadliest air disaster of 2015.Officials said Seif Eddin Mastafa, a 58-year-old Egyptian national believed to suffer from mental problems, was taken into custody in Cyprus after releasing the passengers and crew of the flight unharmed.
