Police escorted Greta Thunberg away from a protest in the abandoned mining village of Lützerath, Germany.
Climate activists occupied the village for days to protest against plans to expand a coal mine.
The Garzweiler lignite mine is expected to be expanded to meet energy needs after Germany announced it would end its dependence on Russian fuel.
The country has promised to phase out coal-fired power generation by 2030, giving a deadline of 2038.
