German police have denied staging photos with climate activist Greta Thunberg at a demonstration against a coal mine on Tuesday.

The denial came after video clips were shared online which appeared to show officers treating Ms Thunberg differently from other activists at the scene.

In one video, two officers pick the Swedish activist up from under the arms as she sits on a bank at the edge of the open-cast mine. They then escort her away in front of photographers before releasing her again a few metres further.

Two other activists, who were sitting close to her, don't receive the same treatment. An officer tells them to move on and they move away, smiling.
