A Turkish official says a passenger claiming there was a bomb on board tried to divert an Istanbul-bound plane to Sochi, Russia, where the Olympics are kicking off.
NTV reports that the plane took off from Kharkov, Ukraine, to Istanbul, and landed safely at Sabiha Gokcen airport.
Authorities are trying to convince the passenger to give himself up. News reports said the plan was a Pegasus Airlines flight.
A spokeswoman for the airline declined comment.
