Greenpeace activists scaled fences to gain entry to an EDF nuclear power plant in Tricastin overnight, demanding it be closed.

The team of over 20 unfurled a banner with the words "Accident nucléaire au Tricastin François Hollande: président de la catastrophe?" ("Tricastin nuclear accident: François Hollande president of the disaster?") above a picture of François Hollande, the French president.

Other activists projected a video of a crack forming on the reactor 1. Greenpeace is asking Mr Hollande to close the Tricastin nuclear power plant, one of the 5 most dangerous facilities in France.
