Greta Thunberg was detained by police at a demonstration in The Hague, in the Netherlands. The climate activist was put in a bus by local police along with other protesters who tried to block a major highway into the city on Saturday. Thunberg had joined a protest by hundreds of activists and was detained when she joined a group of about 100 people who tried to block the A12 highway. Before she was detained, Thunberg said: “We are in a planetary emergency and we are not going to stand by and let people lose their lives and livelihood and be forced to become climate refugees when we can do something.” The 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. At previous protests, police drove detained protesters to another part of the city, where they were released without further consequences. Thunberg was seen flashing a victory sign as she sat in the bus used by police to take detained demonstrators from the scene. The Extinction Rebellion campaign group said before the demonstration that the activists would block a main highway into The Hague, but a heavy police presence, including officers on horseback, initially prevented the activists from getting on to the road. A small group of people managed to sit down on another road and were detained after ignoring police orders to leave. Extinction Rebellion activists have blocked the highway that runs past the temporary home of the Dutch parliament more than 30 times to protest against subsidies. The demonstrators waved flags and chanted: “We are unstoppable, another world is possible.” One held a banner reading: “This is a dead end street.” In February, Thunberg, 21, was acquitted by a court in London of refusing to follow a police order to leave a protest blocking the entrance to an oil and gas industry conference last year. Her activism has inspired a global youth movement demanding stronger efforts to fight the climate crisis since she began staging weekly protests outside the Swedish parliament in 2018. She has repeatedly been fined in Sweden and the UK for civil disobedience in connection with protests.
