Frankfurt Airport, Germany's busiest, faced significant disruptions on Thursday due to climate activists from the group Letzte Generation gluing themselves to the runway, leading to the suspension of all flights for approximately two hours and the cancellation of around 140 out of 1,400 scheduled flights. The protesters breached security by cutting through a fence and used bicycles and skateboards to reach various points on the runway, displaying banners with messages like 'Oil kills.' German authorities condemned the protest, with Interior Minister Nancy Faeser calling it 'dangerous, dumb, and criminal,' while Transport Minister Volker Wissing demanded harsh penalties for such actions. This protest is part of a broader campaign by Letzte Generation, which aims for a global transition away from fossil fuels by 2030 and has planned similar actions across Europe and North America. The protests coincide with record-breaking summer temperatures and growing concerns over climate change's impact. In addition to the Frankfurt protest, similar actions have disrupted traffic at other airports in Europe, including Cologne-Bonn and Oslo.
