In an operation that began on Wednesday, hundreds of police have been removing activists from the doomed hamlet of Lützerath in western Germany.

The clearout had initially been expected to last weeks, but police said on Sunday only two activists remained in the village, holed up in an underground tunnel.

“There are no further activists in the Lützerath area,” they said.

The site, which has become a symbol of resistance to fossil fuels, attracted thousands of protesters on Saturday, including Swedish climate activist Greta Thunberg.

Organisers said that 35,000 protesters demonstrated on Saturday. Police put the figure at 15,000.

Protest organisers reported that dozens had been injured in clashes with police.

Indigo Drau, a spokeswoman for the organisers, on Sunday told a press conference the police had gone in with “pure violence”.

Officers had “unrestrainedly” beaten protesters, often on the head, she said.

Activists on Saturday had accused the police of using “massive batons, pepper spray… water cannons, dogs and horses”.

At least 20 activists had been taken to hospital for treatment, said Birte Schramm, a medic with the group. Some of them had been beaten on the head and in the stomach by police, she said.

Stone-throwing and graffiti

The police said around 70 officers had been injured since Wednesday, many of them in Saturday’s clashes.

“We have been targeted by projectiles, with stones, mud, fireworks,” police spokesman Andreas Mueller told AFP.

“This does not enter anymore into the frame of a peaceful demonstration,” he said.

Several police vehicles were damaged, including by stone-throwing and graffiti, and a large number of tyres on police vehicles were slashed, the police said.

Twelve people were arrested or taken into custody.

Investigations have been launched in around 150 cases, police said, including for resisting police officers, damage to property and breach of the peace.

Many of the activists had been hiding in tree houses and on the roofs of buildings in a bid to complicate the evacuation effort.

Police said they had cleared 35 “tree structures” as well as around 30 wooden constructions.

Lützerath — deserted for some time by its former inhabitants — is being demolished to make way for the extension of the adjacent open-cast coal mine.

The mine, already one of the largest in Europe, is operated by energy firm RWE.

The expansion is going ahead in spite of plans to phase out coal by 2030, with the government blaming the energy crisis caused by Russia’s invasion of Ukraine.
