CLIMATE activists disrupted flights at Frankfurt Airport, Germany’s busiest, today as they glued themselves to the ground inside the airport premises, authorities said. 

More than 100 flights were cancelled.

Federal police said several demonstrators got into the airport in the early morning, German news agency dpa reported. 

The Last Generation group said six protesters had cut holes in the perimeter fence and headed toward the runways on foot, bicycles and skateboards.

The airport said about 140 flights had been cancelled, roughly a tenth of the flights that were scheduled for Thursday.

It was the second time in as many days that a protest by Last Generation, which is demanding that the German government negotiate and sign an international agreement on a global exit from the use of oil, gas and coal by 2030, caused disruption at a major German airport.

On Wednesday, five protesters glued themselves to a taxiway at Cologne-Bonn Airport, forcing a roughly three-hour halt to flights. That protest resulted in 31 flights being cancelled. 

There were other protests or attempted protests in other European countries.

Last week, the German cabinet approved legislation that would impose tougher penalties on people who break through airport perimeters including punishments ranging up to a two-year prison sentence.
