At least nine people were killed and hundred others injured in the violence that took place in several states as protesters blocked trains, clashed with police and set fire to private and public properties, including police posts, during a nationwide bandh called by Dalit groups on Monday, officials said. Thousands were detained across over 10 states, several of them being BJP-ruled, including Madhya Pradesh where at least six people died during the protests against the alleged dilution of the SC/ST (Prevention of Atrocities) Act.
