London: A group of environmental campaigners opposed to the expansion of London's Heathrow Airport disrupted access for passengers to Europe's busiest hub on Thursday, police and airport officials said.
Police said they had arrested five people and taken away three vehicles used in the protest against plans to build a third runway at Heathrow which are currently under consideration.
"There is a protest taking place in the inbound tunnel which is currently affecting traffic around the central terminal area and terminals 2 and 3 at Heathrow," a Heathrow spokesman said.
"Police are on site but we advise passengers to allow extra time getting to the airport on Thursday."
Drivers arriving at the airport were being re-routed to avoid the protesters and passengers told to go to other terminals.
"Airport expansion would wreck the legally-binding Climate Change Act," said Cameron Kaye, a spokesman for environmental campaign group Plane Stupid.
"The government needs to choose: build new runways or stop climate chaos: it's that simple," he added.
