Major roads in central London have been blocked for a second day by climate change protests, which have seen more than 120 people arrested.
On Monday morning, a group of demonstrators with trees, plants and solar panels in tow barricaded Waterloo Bridge, one of five locations being targeted by environmental campaigners in the city as part of the protest.
Police said the rallies caused significant disruption to 55 bus routes and affected roughly 500,000 people.
It said those arrested included five people detained on suspicion of criminal damage in south London's Lambeth area, where protesters vandaliced oil giant Shell's office, spraying slogans including "climate criminals" on the front of the building.
Dozens of protesters were dragged away from Waterloo Bridge by police officers at around 1pm on Tuesday. It took police several hours to remove them. "So we're pulling out all stops and rising up in a full-scale rebellion against this twisted system to save ourselves and the natural world from extinction".
Demonstrators arrived at London's Hyde Park yesterday, some having journeyed to the city on foot in recent weeks from various parts of the UK.
Organisers said: "The worldwide rebellion begins and Extinction Rebellion will be bringing London to a standstill for up to two weeks".
Next round of strong storms arrives late Wednesday - Wednesday night
Heavy rain from the thunderstorms may lead to isolated instances of flooding and a "short-lived tornado" is also possible. The Storm Prediction Center says trees and power lines are down in Brewton near the Florida line, and some power is out.
The campaign group described those arrested as "brave rebels".
Police carried some protesters off Waterloo Bridge.
The protesters stationed themselves under the vehicle with blankets and sleeping bags, and have vowed to remain there for as long as possible.
Ben Moss, 42, from Islington, north London, glued himself to the bars of the lorry.
Blythe Pepino, 34, from Hereford, said: "The objective is to maintain the disruption on the bridge to bring the Government to the table and talk about the climate crisis".
"I'm doing this because I want the Government to do something".
"We are mindful of the impact the demonstrations are having on the local communities and are working hard with partners including TfL to keep London moving and open for businesses and visitors alike. The only grief we've had is from passing motorists shouting at them to "Get a job" - that's about as exciting as it's got".
