Members of the Just Stop Oil group have glued themselves to a copy of Leonardo da Vinci's The Last Supper painting in protest over fossil fuels, resulting in a part of the Royal Academy art gallery being shut down.
"No New Oil" has been spray-painted underneath the artwork and five protesters have glued their hands to the frame at the London art gallery.
The Royal Academy said that police have been called to the scene and as of Tuesday afternoon, the five protesters remained attached to the painting.
According to the group Just Stop Oil, Lucy Porter, 47, a former primary school teacher is among the five who have glued themselves.
She said: "When I was teaching, I brought my students to great institutions like the Royal Academy. "But now it feels unfair to expect them to respect our culture when their government is hellbent on destroying their future by licensing new oil and gas projects.
"We have no time left, to say that we do is a lie."
Ms Porter demanded that all new oil and gas exploration be stopped, saying that the group "will stop disrupting art institutions as soon as the government makes a meaningful statement to do so."
"Until then, the disruption will continue so that young people know we are doing all we can for them. There is nothing I would rather be doing."
