Police in the Netherlands surrounded a passenger jet which landed at Schiphol Airport, outside Amsterdam, in the mistaken belief that there was a hijacker on board.
The airliner has been escorted in to land by two military fighters.
Initially it was thought the plane had been taken over en route from Malaga in Spain to Schiphol Airport.
The plane, said to be from airline Vueling, was escorted to Schiphol by two F16 fighter jets scrambled from the Netherlands.
But later reports said there had been a communications mix-up and the airliner had not been hijacked.
Earlier this morning, part of the airport was evacuated today after workers unearthed a suspected Second World War bomb near its main terminal building.
The airport's Pier C was shut down for arriving and departing flights while military bomb disposal experts checked the suspected explosive and decided what to do with it.
The airport said the pier's closure could lead to delays and cancellations of flights.
The suspected bomb was uncovered by workers digging near the pier, which houses many of Schiphol's departure and arrival gates.
Schiphol, just outside the Dutch capital, is one of Europe's busiest aviation hubs.
