The violence in the Cauvery water dispute claimed its second life today, as an uneasy calm hung over worst-hit Bengaluru amid sporadic protests in Karnataka and Tamil Nadu marked by targeted attacks. Prime Minister Narendra Modi expressed pain over the attacks in the two states locked in a bitter river water sharing row and appealed for calm while stressing that violence cannot provide solution to any problem. He asserted that the dispute can only be solved within the legal ambit and "breaking the law is not a viable alternative".
