In London the National Gallery said that Van Gogh’s Sunflowers is covered with glass and was not damaged when protestors threw tins of Heinz Tomato Soup at it today. There is some minor damage to the frame of the work, painted in 1888. The two climate activists in Just Stop Oil T-shirts opened the tins and threw the contents on the masterpiece before gluing their hands to the wall. The Metropolitan Police said two people had been arrested.
