NEW DELHI (AFP) - A Jet Airways flight from Mumbai to Dubai made an emergency landing in Muscat on Thursday after a bomb threat, an official said, in the second such incident in two days.

All 54 passengers and seven crew members were evacuated once the plane landed safely in an isolated area at Muscat's international airport, a senior Jet Airways spokesman told AFP.

"There was a bomb threat on the flight. It was a serious threat prompting the pilot to land at the closest airport," said Manish Kalghatgi.

"All guests and crew disembarked without any incident and were taken to the airport terminal," Kalghatgi said.

The plane continued it journey after the aircraft and all baggage and cargo were searched by the Omani security agencies.

Jet Airways is one of India's biggest airlines with a fleet of 116 aircraft.

On Tuesday, a Turkish Airlines flight from Bangkok to Istanbul made an emergency landing in New Delhi after a bomb threat was scrawled in lipstick on a bathroom mirror.

It was the third such bomb threat to affect Turkish Airlines this year alone.
