From Paris's Liberation to 'arresting' art in Avignon

In this look at the week’s art news we start with an exhibition that remembers the story of how Paris was freed from the Nazis 70 years ago. Then we head to Avignon in the south of France, where the prestigious Lambert Collection has been moved behind bars to a disused prison while its home is closed for expansion. We also follow the "Girl With The Pearl Earring" back home to Holland and admire Jimmy Nelson’s striking photographs of the world's last tribesmen.
