Berlin Brandenburg Airport said on Thursday flights were resuming with some delays after being forced to close its runway when climate protesters entered the site and some of them clung to the runway.

Activists from the environmental group Last Generation appealed to the public to stop traveling by air and called on the government to end its subsidies.

“In areas of the airport which are not open to the public, we met several people who had previously gained unauthorized access and some were clinging (to the tarmac),” Berlin police said on Twitter.

The latest protest by climate activists in Germany also urged the government to expand its offer of cheap rail travel.

“The wealthy one percent of the population is responsible for around half of aviation-related greenhouse gas emissions,” Last Generation said in a statement, adding that a 70-year-old man was among the activists at the airport.

An airport spokesman said the activists entered the airport from two points to the north and south, and police detained them.

The spokesperson could not say how many flights were affected.

Flight tracking website FlightRadar24 shows several planes that were originally headed to the airport changing their routes.

Some 13 flights had been diverted to airports in the eastern state of Saxony as of 6pm (1700 GMT), broadcaster rbb reported, citing Mitteldeutsche Flughafen AG, the company which operates airports in Dresden and Leipzig.
