Climate protesters stormed a runway at Berlin’s Brandenburg Airport and stuck themselves to the tarmac, causing it to temporarily close and delay flights.
Berlin police said they encountered “several people” in an area not open to the public, after the activists gained unauthorized access, some of whom pinned themselves to the ground.
Activists from environmental group Last Generation, who say a 70-year-old man was among the participants, were also seen cycling through the diversion area – bringing air traffic to a standstill.
Video shows members of the group climbing through a wire fence that has been cut down to reach the runway.
The group called on the public to stop air travel and called on the government to stop subsidizing it.
Last Generation said in a statement: “Airplane is not a means of transportation for ordinary people, and most people – about 80% – have never flown.
“The richest one percent of the population is responsible for about half of aviation-related greenhouse gas emissions.”
The airport said that flights had resumed with some delays, after being forced to close their runways.
An airport spokesman said the activists had entered from two points, north and south, and that police had detained them. They added that they could not say how many flights were affected.
Flight-tracking website FlightRadar24 showed that some planes originally headed for the airport had changed course.
Michael Hasemer, a judge at the Constitutional Court of Rhineland-Palatinate, said he considers the resistance of the last generation to be justified by the climate emergency.
“The consequences for humanity of not taking climate protection measures are in no way so grave that legal obstructions by invocation are to some extent justified by states of emergency and are therefore acceptable,” he said.
About 13 flights had been diverted to airports in the eastern state of Saxony by 5pm GMT, RBB reported, citing Mitteldeutsche Flughafen AG, the company that operates airports in Dresden and Leipzig.
The protest, the latest by climate activists in Germany, urged the government to expand offers of cheap train travel.
