Climate activists from the group Last Generation disrupted operations at Frankfurt Airport, Germany's busiest hub, by breaching security and gluing themselves to the runway, resulting in the cancellation of approximately 140 flights. The protest, which took place during the peak summer travel season, triggered responses from police and airport security, leading to the arrest of eight demonstrators. Frankfurt Airport condemned the unauthorized actions, citing severe risks to flight safety and announcing plans for potential legal action against the activists. Similar protests occurred at Cologne-Bonn Airport and across other European airports, as environmental groups call for an end to fossil fuel extraction and burning by 2030. The protests coincide with alarming climate data highlighting record heat levels and increasing fossil fuel investments, despite global climate commitments. Authorities are also considering new legislation to impose stricter penalties on airport trespassers amid ongoing disruptions.
