Greta Thunberg detained by police at German coal protest

• She and other protesters were physically removed from the site Sunday.

Details: Thunberg was participating in a sit-in near the edge of the mine on Tuesday when she and other activists were detained. One activist had jumped into the mine, Reuters reported.

• Three police officers escorted Thunberg from the site and towards a set of police vans.
• Police began on Wednesday clearing the area of hundreds of protesters, some of whom had barricaded themselves into the largely uninhabited village's structures, erected watchtowers, camped out in trees and even created a tunnel network.

The big picture: Lützerath has become a symbol of the climate movement in Germany. It's been occupied by protesters in recent years years after the town's residents were evicted to make way for the coal mine's long-planned expansion, CNN reported.

• Activists argue that the mine's expansion will release large amounts of greenhouse gases and help prevent Germany from meeting its commitments to the Paris climate agreement, per NBC News.
