More than 200 people have been arrested in ongoing climate change protests in London that brought parts of the British capital to a standstill, police said Tuesday.
Demonstrators began blocking off a bridge and major central road junctions on Monday at the start of a civil disobedience campaign that also saw action in other parts of Europe.
The protests were organised by the campaign group Extinction Rebellion, which was established last year in Britain by academics and has become one of the world's fastest-growing environmental movements.
London's Metropolitan Police said that by Tuesday evening, 209 arrests had been made.
"We expect demonstrations to continue throughout the coming weeks," the police statement said.
The arrest figure includes three men and two women who were detained at the UK offices of energy giant Royal Dutch Shell on suspicion of criminal damage.
Campaigners daubed graffiti and smashed a window at the Shell Centre building.
The majority arrested were seized for breaching public order laws and obstructing a highway.
The protest saw more than a thousand people block off central London's Waterloo Bridge and lay trees in pots along its length. Later, people set up camps in Hyde Park in preparation for further demonstrations throughout the week.
- Police restrictions -
The police have ordered the protesters to confine themselves to a zone within Marble Arch, a space at the junction of Hyde Park, the Oxford Street main shopping thoroughfare and the Park Lane street of plush hotels.
"We so far have 55 bus routes closed and 500,000 people affected as a result," the police said.
Campaigners want governments to declare a climate and ecological emergency, reduce greenhouse gas emissions to zero by 2025, halt biodiversity loss and be led by new "citizens' assemblies on climate and ecological justice".
Extinction Rebellion spokesman James Fox said the group had attempted to maintain a blockade overnight at four sites in central London before the police came to impose the new restriction.
Protesters attached themselves to vehicles and to each other using bicycle locks, said the spokesman.
"We have no intention of leaving until the government listens to us," he said.
"Many of us are willing to sacrifice our liberty for the cause."
