Extinction Rebellion activists have blocked major roads in London and other cities across Europe at the beginning of what was billed as a wide-ranging series of protests demanding new climate policies.
Activists in London say they expect the protests to be as much as five times bigger than those held in April, which brought major disruption to London and saw more than 1,100 arrests.
The group claims protests are planned in 60 cities worldwide, including Madrid, Berlin, Amsterdam and Sydney.
Here are some of the scenes from protests around the world:
Police were also searching anyone suspected of carrying paint.
Drumming, whistles and chanting rang through the streets of London as protesters attempted to block the routes into the center of Government around Parliament and Whitehall.
Dozens of people were arrested in connection with the protests.
Protests were also held outside Government departments, calling on them to outline what their plans are to tackle the climate emergency, along with processions, marches and a sit-in at City Airport.
Hundreds of protesters filled Trafalgar Square and planned to shut down roads around Parliament Square and Whitehall.
Protesters chained and glued themselves to Victoria Street, outside Westminster Abbey.
They want to see the Government create and be led by the decisions of a Citizens’ Assembly on climate and ecological justice.

Extinction Rebellion is calling on the Government to declare a climate and ecological emergency, to act immediately to halt wildlife loss and to reduce greenhouse gas emissions to net-zero by 2025.
