UK climate change protests
Two men have been arrested at Heathrow as climate change protesters tried to launch drones within the airport's exclusion zone.
Heathrow Pause said it intended to fly drones in the 5km exclusion zone around the airport on Friday morning.
A Heathrow spokesperson said: “Heathrow’s runways and taxiways remain open and fully operational despite attempts to disrupt the airport through the illegal use of drones in protest nearby.
"We will continue to work with the authorities to carry out dynamic risk assessment programmes and keep our passengers flying safely on their journeys today.
“We agree with the need for climate change action but illegal protest activity designed with the intention of disrupting thousands of people, is not the answer.
“The answer to climate change is in constructive engagement and working together to address the issue, something that Heathrow remains strongly committed to do.”
The Global Commission on Adaptation - a group of 34 leaders in politics, business and science say the world urgently needs to be made more "climate change resilient".
