One of Germany`s principal airports, Dusseldorf International, was back in business Monday after bomb threats caused a six-and-half hour closure yesterday.
A series of telephoned threats were made to the airport on Sunday, setting off a full scale security alert which affected thousands of passengers and around 150 flights.
The callers are reported to have threatened to blow up aircraft as well as targeting airport buildings.
All three terminals at the country`s third largest airport were closed down while police teams carried out searches. No explosives were found but a number of controlled explosions were carried out.
Incoming flights to Dusseldorf were diverted to other airports.
This was the second security scare in 48 hours at a European airport. On Friday, London Gatwick South Terminal was closed for several hours after a suspect car was discovered in a road tunnel which runs underneath the building.
The vehicle was examined by an Army bomb team, but no explosives were found. Three people were later detained by police in connection with the incident.
