Mona Lisa smeared in cake in climate protest attack

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.
