West Bengal Chief Minister Mamata Banerjee, and Union Home Minister Amit Shah engaged in a war of words a day after violence marred polling in Cooch Behar. Two incidents led to deaths of 4 people. In one incident, a mob allegedly attacked CISF personnel, who responded with firing. In another incident, an 18-year-old was killed in an alleged BJP-TMC clash. Shah held Banerjee responsible for the violence due to her 'inciting' speech. Mamata, however, called the firing by central forces 'genocide'. Watch the full video for more.
