Climate change protesters block major Heathrow Airport tunnel (VIDEO)

Climate change protesters have blockaded a motorway tunnel leading to Heathrow Airport in protest against a planned third runway being built. Major delays on the M4 are causing chaos for airport passengers.

Activists used a vehicle to block the tunnel leading to the airport before chaining themselves to it and lying down on the road on Tuesday morning.

The blue car had a banner on it reading “no new runways.”

Two drivers of two other vehicles blocking the tunnel have been arrested, according to the Evening Standard, while officers work to remove the people attached to the third car.

The protest was staged by campaign group Rising Up, which works to tackle climate change.

The group streamed the protest live from its Facebook page. It said it staged the protest because the consultation for the airport expansion proposal was “illegitimate and undemocratic.”

Motorists and holidaymakers have taken to social media to vent their frustration.

“The actions of these protesters are selfish, short-sighted and counterproductive. Most local communities living near Heathrow support expansion and passengers simply want to be able to use the airport in peace,” said Campaign group Back Heathrow, which supports the airport’s expansion.

A spokesman for Heathrow Airport said that “Heathrow Airport can confirm that a protest activity is on-going in the inbound tunnel to Terminals 2 and 3.

“Heathrow supports the right to peaceful protest within the law, but the safety and security of our passengers, aircraft and colleagues together with the smooth running of the operation is paramount.

“Contraflow traffic measures are in place and we are working closely with the authorities to resolve the issue, but advise passengers to allow more time to drive into Terminals 2 and 3.”

The plan to build a third runway at Heathrow was agreed in October as the government’s preferred option for increasing capacity in southeast England.
