Now, Dutch police have arrested several climate activists who attempted to block a main road in The Hague. Those detained included the Swedish campaigner Greta Thunberg. Our correspondent, Anna Holgen, was there.

The final few climate activists have just packed up their banners and are preparing to go home. Earlier, there were cries, cheers of You are not alone as Greta Thunberg was picked up off the highway by Dutch police and put on to a minibus, along with hundreds of other protesters. You can see her here chatting happily to fellow activists. She's here in The Hague to announce international actions against governments who make it cheap and easy for large companies to use fossil fuels by offering them tax breaks and subsidies on excise juices. Greta Thunberg describes her arrest as peaceful. Most of the protesters have gone home or been detained by police and taken away in minibusses. Police are just keeping watch to make sure that nobody else tries to block this highway, the A12 in The Hague.
