Climate protester smears Mona Lisa in cream

STORY: The perpetrator was a man disguised as an old lady who jumped out of a wheelchair before attacking the glass.

"Maybe this is just nuts to me...," posted @klevisl007 on Twitter, the author of a video of the incident's aftermath that shows a Louvre staffer cleaning the glass.

"(He) then proceeds to smear cake on the glass, and throws roses everywhere before being tackled by security."

The Louvre was not immediately available for comment.

Another video posted on social media showed the same staffer finishing cleaning the pane covering the Da Vinci masterpiece while another attendant is seen removing a wheelchair from in front of the painting.

"Think of the earth; people are destroying the earth", the man, dressed in a wig, said in French in another video posting that showed him being led away from the Paris gallery with the wheelchair, indicating that the incident likely had an environmentalist motive.
