A previously unknown landscape painting by Vincent van Gogh has been identified by the Van Gogh Museum in Amsterdam.
Sunset at Montmajour - which depicts trees, bushes and sky - had spent years in a Norwegian private collector's attic after he had been told the work was not by the Dutch master.
Watch the moment Van Gogh museum director Axel Ruger unveiled the painting.
