Stockholm, Sweden:
Police closed part of Stockholm's main international airport on Tuesday amid media reports of a bomb threat.
"There has been a threat and we have taken measures," police spokesman Lars Bystroem told AFP, without giving further details.
"It's not the first time we've received this kind of threat but it is not very common," he said, adding that flights were still taking off with slight delays.
An airport spokesman told TT news agency that the threat involved a suspicious piece of luggage and that several gates had been closed.
A passenger told public broadcaster Sveriges Radio that police had evacuated a plane headed for Copenhagen following a bomb threat.
Other unconfirmed reports said that police had taken a suspect into custody following a threat to an aircraft.
