The 16th Century painting by Leonardo da Vinci sits behind protective glass at the Louvre in Paris.

Protesters have thrown soup at the glass-protected Mona Lisa painting in Paris.

The perpetrator urged people to "think of the earth" while being led away from the scene.

The statue was made by a street artist after a challenge from Banksy.

The painting gained fame when its owner challenged the Louvre to prove it had the true Mona Lisa.
