The protests in Jaitapur (Maharastra) attempt to stop a massive nuclear project by French nuclear giant Areva (involved in the Fukushima disaster) and the state-owned Indian nuclear corporation. The power plant intends to be the largest in the World and is located in a seismically active area.
Protests have been going on since 2009 but have acquired new virulence after the Fukushima catastrophe. Yesterday police murdered a protester, what has only caused anger to increase.
