In an apparent jibe at BJP leaders, West Bengal Chief Minister Mamata Banerjee on Monday said that those threatening of more Cooch Behar-like killings should be banned politically. While addressing an election rally at Ranaghat in the Nadia district, Banerjee said, "Some political leaders are threatening of more Sitalkuchi-like incidents, while others are saying that the death toll should have been higher. I am stunned and shocked to see such reactions. What are these leaders up to? They should be politically banned.”
