Climate change protesters have thrown soup over Vincent van Gogh’s painting “Sunflowers” at London’s National Gallery, the Just Stop Oil campaign group says.

A video posted by the group, which has been holding protests for the last two weeks in the British capital, showed two women throwing two tins of Heinz tomato soup over the painting, one of five versions on display in museums and galleries around the world.

“Officers were rapidly on scene at the National Gallery this morning after two Just Stop Oil protesters threw a substance over a painting and then glued themselves to a wall,” police said on Twitter.

Both have been arrested for criminal damage and aggravated trespass.

The gallery had no immediate comment.

Just Stop Oil said the painting, which dates to 1888, has a value of $A134 million).

The group’s activists have been blocking roads around parliament in the last few days.

Last Sunday, police said that more than 100 people had been arrested after a weekend of protest-related activity by environmental groups.
