Two environmental activists glued themselves to an exhibition of a dinosaur skeleton at Berlin's Natural History Museum on Sunday to protest the German government's climate policies.

It was the latest such stunt by climate campaigners at a museum, after famous artworks were targeted in different ways across Europe.

In Berlin, two women wearing orange vests stuck themselves to metal poles supporting a dinosaur skeleton that was over 60 million years old, holding a banner that read: "What if the government doesn't have it under control?"

One of the women, Caris Connell, said she was scared of "forest fires, water shortages, famines, and war.

"Dinosaurs died out, because they could not withstand massive changes to the climate. That is also threatening us," added the 34-year-old.

The other activist, Solvig Schinkoethe, said as a mother of four, she feared the consequences of climate change. 

"Peaceful resistance is the way we have chosen to protect our children from the deadly ignorance of governments," said the 42-year-old.

They called on the government in Berlin to take quick steps to cut emissions, such as by setting a speed limit on motorways and introducing more affordable public transport. 

The museum said police brought the incident to an end in under an hour. There was property damage, and criminal charges have been filed, it said in a statement. 

The activists were from the group Last Generation, which earlier this month splashed mashed potatoes on Claude Monet's $111-million "Les Meules" (Haystacks) at the Museum Barberini in Potsdam, Germany.

Meanwhile, a young woman tried to throw soup at a painting at the world-famous Musee d'Orsay in Paris this week, the museum confirmed Sunday.

The museum refused to say which painting was targeted but it is home to artwork by some of the most famous European artists including Paul Cezanne, Paul Gaugin, Vincent van Gogh, Edouard Manet and Claude Monet.

The museum told AFP it had filed a legal complaint for the "attempt to damage a piece of work" after the female activist was intercepted on Thursday, confirming a report in Le Parisien daily.

The Paris prosecutor's office said police had opened an investigation after the complaint.

According to Le Parisien newspaper, the woman had initially tried to approach the 1889 Van Gogh self-portrait at Saint-Remy before attempting to throw soup at a painting by Gaugin.

The daily reported she was wearing a "Just Stop Oil" T-shirt, as others have worn during similar stunts in recent weeks.

On Thursday, climate activists glued themselves to Johannes Vermeer's "Girl with a Pearl Earring" at the Mauritshuis museum in The Hague, Netherlands.

Environmental activists splashed tomato soup on Van Gogh's "Sunflowers" at the National Gallery in London earlier this month, while others threw mashed potato over a Monet painting at the Barberini Museum in Germany. 

As the attacks multiply, French Culture Minister Rima Abdul Malak has urged national museums to "redouble their vigilance".
