LONDON — Two climate protesters were arrested Wednesday for spraying orange paint on the ancient Stonehenge monument in southern England, police said.

The latest act by Just Stop Oil was quickly condemned by Prime Minister Rishi Sunak as a “disgraceful act of vandalism.”

Video of the incident showed two people running towards the 4,500-year-old stone circle and spraying plumes of orange pigment as a third person attempted to stop them. A few stones were smeared in orange.
