Climate activist Greta Thunberg has been arrested by Dutch police at a climate protest at The Hague. 

She was among dozens of people arrested after trying to block a major highway into The Hague. 

Hundreds of Extinction Rebellion activists attempted to block the A12 highway, but the majority were blocked by police. 

Ms Thunberg was among a small group of people who managed to sit down on another road. 

The protestors were detained after ignoring police orders to leave.

That A12 highway 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. 

Extinction Rebellion activists have blocked the road that runs past the temporary home of the Dutch parliament more than 30 times to protest against the 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.” 

At previous protests police drove detained protesters to another part of town, where they were released without charge. 

In February, Ms Thunberg, aged 21, was acquitted by a court in London of refusing to follow a police order to leave a protest blocking the entrance to a major oil and gas industry conference last year. 

She has repeatedly been fined in Sweden and the UK for civil disobedience in connection with protests.
