European authorities say they arrested more than 250 climate activists Monday as the Extinction Rebellion group kicked off its latest wave of protests, staging a series of demonstrations that one top German official criticized as being partly "dangerous". "But if you announce unsafe interventions in road traffic or things like this, of course that is just not on".
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".
New York City police officers surrounded the group and began making arrests after the protesters blocked tourists.
Tony Whitehead, one of the protesters from Dartmoor, said: "We need DEFRA to start telling the truth about the devastating effects of the food system on both people and the natural world".
"In the United Kingdom, we will peacefully shut down all roads into Westminster in Central London and non-violently disrupt the government until our leaders agree to TAKE EMERGENCY ACTION NOW", the group says on its website.
Ardern supported the group's right to protest, and said there was a place for demonstrations that are non-violent and legal.
These Parisian activists have been occupying this central position, a few hundred metres from the Paris police prefecture, where a ceremony was organized on Tuesday in honour of the victims of last week's massacre, in the presence of Emmanuel Macron.
Extinction Rebellion (XR for short) wants governments to declare a "climate and ecological emergency" and take immediate action to address climate change.
In June, during an action to block another bridge in Paris, Extinction Rebellion members were moved on by the police using tear gas at close range.
Among those arrested was 81-year-old Sarah Lasenby, a retired social worker from Oxford.
As protests got under way in the capital, police were seen cutting two Extinction Rebellion protesters out of a vehicle blocking off Victoria Embankment. "We have a narrow window of time where we can take significant action".
Thirty people were charged with committing offences in Sydney after hundreds blocked a road, while more than 100 were arrested in Amsterdam.
Earlier in London, police said some 135 climate activists were arrested. Some were seated, some chained to a barrel.
