Around a thousand protesters from action group Extinction Rebellion gathered on Stadhouderskade, at the Rijksmuseum, from around 5:00 a.m. on Monday morning to demonstrate for a more effective climate policy.

"Some might call us protesters, I call us protectors", said spokesperson Simon Oosterman.

Back in April, members of the group blocked several London roads and bridges during 10 days of action created to alert the public and politicians to the "climate emergency".
It's all to protest climate change.
More than 1,000 protesters were arrested in April following an 11-day demonstration in London.
The demonstration went ahead despite the city banning activists from gathering on the road.
Extinction Rebellion called for more provisions amid an uptick of arrests and confiscations by the police, appealing to "more Londoners to join us as we head towards a chilly evening".
Some 60 events were planned around the world on Monday and in Germany they were keen to kick off proceedings early.
