Climate activist Greta Thunberg was detained by police at a large climate demonstration in The Hague, the Netherlands, on Saturday.
After being held for several hours she was released again in the evening, a spokesperson for protest organizers Extinction Rebellion told Reuters.
Activists were blocking a highway
Activists had been trying to block the nearby A12 highway. That road has been blocked for several hours dozens of times in recent months by activists demanding an end to all subsidies for the use of fossil fuels.
Local police would not comment on individual cases but said everyone who tried to block roads was detained. On social media site X, police posted that 412 protesters had been detained, mostly for participating in a banned protest.
