Amsterdam, 5 November 2022 (dpa/MIA) — A third climate activist has been sentenced to two months in prison after pouring what appeared to be tomato soup on another activist who had glued his head to the world-famous "Girl with a Pearl Earring" painting by Johannes Vermeer in protest of the fossil fuel corporations destroying the planet. One month of the sentence was suspended, a court in the Dutch city ruled on Friday. The glazed painting in the Mauritshuis museum in The Hague had not been damaged during the action. The protester, who is from Belgium, had poured a can of red substance on another climate activist in the Mauritshuis last week and then glued his hand to the wall behind the painting. During the protest, he said the Vermeer painting was protected behind glass. "The future of our children is not protected," he added. The climate activist said he had regretted the act before the judge. His defense lawyer announced that he would appeal against the verdict. The two other men involved in the action had already been sentenced to two months in prison on Wednesday evening. One of them appealed against the sentence. One of the activists had stuck his head to the glass of the frame while the other had filmed the action. The protesters belong to the climate protection movement Just Stop Oil.
