Just Stop Oil activists have thrown tomato soup over Van Gogh’s masterpiece Sunflowers at the National Gallery.
Two women walked into a room at the gallery in Trafalgar Square at about 11am, the campaign group said.
They threw the contents of two tins of Heinz tomato soup over the painting, which has an estimated value of £72.5m.
They then appeared to glue one hand each to the wall below the painting, before one shouted: “What is worth more? Art or life?
“Is it worth more than food? Worth more than justice?”
Gasps and and exclamations of “oh my gosh!” and “security” ran out from onlookers as the soup hit the painting.
