A man seemingly disguised as an old woman in a wheelchair threw a piece of cake at the glass protecting the Mona Lisa at the Louvre Museum and shouted at people to think of planet Earth.

The cake attack left a conspicuous white creamy smear on the glass but the famous work by Leonardo da Vinci wasn't damaged.
Security guards were filmed escorting the wig-wearing activist away as he called out to the surprised visitors in the gallery: "Think of the Earth. There are people who are destroying the Earth. Think about it. Artists tell you: think of the Earth. That's why I did this."
Guards were then filmed cleaning the smeared cream from the glass. Officials at the Louvre weren't immediately available for comment.
