The Mona Lisa was left shaken but unharmed when a visitor to the Louvre tried to smash the glass protecting the world's most famous painting before smearing cake across its surface in an apparent climate-related publicity stunt.
The perpetrator was a man disguised as an elderly woman who jumped out of a wheelchair before attacking the glass.
'Maybe this is just nuts to me,' @klevisl007 posted on Twitter, along with a video of the incident's aftermath that shows a member of staff at the Louvre cleaning the glass
