STORY: They streamed their action live on Twitter and Youtube: Climate activists from the group “Last Generation” broke into the airfield of Berlin Airport BER without authorization on Thursday. The stream showed how the demonstrators snapped through a fence and entered the airport area. They then held banners up to the camera and explained their motives. It was also seen how some action participants glued themselves to the ground. Blue lights could also be seen later, and police officers could also be heard. The activists appeared to have entered the airport site in two places, both on the north and south sides, an airport spokesman said. Flight operations were suspended because of the protest action. “Because of the unauthorized access of several people, both runways at BER are currently closed,” tweeted the airport operator. Several machines then headed for other airports, others turned holding patterns, as can be seen on the Flightradar24 flight observation site. An airport spokesman was unable to provide any information on the number of flights affected. Early Thursday evening it was said that flight operations on both runways had resumed. But there are still delays.
