Just Stop Oil activists have targeted Stonehenge the day before the Summer Solstice in an act of vandalism the group says is a demand for the UK government to "commit to working with other governments to agree an equitable plan to end the extraction and burning of oil, gas and coal by 2030".
As seen in dramatic images from the Unesco World Heritage site in Wiltshire, the stones have been daubed with orange powder paint in what the protest group calls "megalithic action" to raise awareness on climate change.
Niamh Lynch, 21, a Student from Oxford, was involved in the incident today, and said: "Stonehenge at solstice is all about celebrating the natural world - but look at the state it's in!
"We all have a right to live a life free from suffering, but continued burning of oil, coal and gas is leading to death and suffering on an unparalleled scale.

"It's time for us to think about what our civilisation will leave behind - what is our legacy?
"Standing inert for generations works well for stones - not climate policy."
