 On the first anniversary of the Fukushima nuclear disaster, organisers of French anti-nuclear demonstrations claim 60,000 supporters formed a human chain 230 kilometres long, stretching from Lyon to Avignon.In March 2014, police arrested 57 Greenpeace protesters who used a truck to break through security barriers and enter the Fessenheim nuclear power plant in eastern France.The activists hung antinuclear banners, but France's nuclear safety authority said that the plant's security had not been compromised.
