In a move to bring attention to the urgency of climate change, two German protestors on Sunday threw mashed potatoes at a Claude Monet painting. The work, titled "Grainstacks," had previously sold for over $110 million.

The incident occurred at the Barberini Museum in Potsdam, the capital of the state of Brandenburg, about 20 miles southwest of Berlin.

"This painting is not going to be worth anything if we have to fight over food," one of the two activists protesting climate change said.

Authorities are investigating the protestors for property damage and trespassing. The painting was unharmed because it was covered with protective glass, the museum said.

Letzte Generation, meaning "last generation," a German group advocating for climate change awareness, claimed responsibility for the protest at the museum.

Police in Brandenburg said the protestors were arrested before being released later.

"Endangering pictures in museums and wantonly accepting their destruction is not a contribution to climate protection," said Ortrud Westheider, director of the Barberini Museum.

In a similar incident earlier this month, protesters in London doused a Van Gogh painting with what seemed to be tomato soup.

The museum said it expects to have the painting back on display on Wednesday.
