Moscow - A drunk man triggered a hijack alert aboard a domestic flight to Moscow from the Black Sea resort of Sochi on Friday, the news agency Interfax reported.

The agency first cited an unnamed police officer as saying a passenger on board a Boeing 737 owned by Russian low-cost carrier SkyExpress had threatened to detonate a bomb with the cry of Allahu Akbar if the plane was not re-routed to Vienna, Austria.

Russia's Emergency Situations Ministry said it sent five ambulances to Moscow's Vnukovo airport before the flight landed.

"Immediately after takeoff the flight crew signaled it had been hijacked and again confirmed the information later during the flight," airline spokesman Vitaly Korenyugin was quoted as saying.

The airliner carrying 132 passengers landed safely at 6:05 pm Moscow time (1405 GMT), he said.

Russia's FSB security services said they were on standby to arrest the inebriated passenger.

The incident comes one week after a similar scare aboard a Turkish airline flight to St Petersburg. (dpa)
