Banksy mural criticises treatment of Calais migrants

The latest artwork by Banksy artwork has criticised the apparent use of teargas on migrants in the Calais "Jungle" camp.

The mural - which has since been boarded up - was painted opposite the French Embassy in London's Knightsbridge.

Based on a poster for musical Les Miserables it shows a girl with tears in her eyes as a can of CS gas lies beneath her.
