Authorities in Germany briefly shut an airport and scrambled fighter jets to escort a passenger plane after an emergency call raised fears of a possible hijacking but turned out to be over a radio problem, officials said.

As reported by news agency AP, the carrier, Corendon Airlines, said that the Boeing 737-800 flying from Corfu, Greece, to Nuremberg, Germany, sent out an emergency code late in the morning over Croatia "due to a brief malfunction in the radio communication system".
