A day after West Bengal Chief Minister Mamata Banerjee called the Delhi violence a 'planned genocide' and blamed the BJP for the disturbances, the saffron party hit back on Tuesday with union minister Babul Suriyo asking the Trinamool Congress supremo to stop making 'provocative comments'.

Supriyo alleged that Banerjee did not even know the meaning of 'genocide' and should think twice before shooting off her mouth.

"The chief minister doesn't even know the meaning of genocide. So she should think twice before shooting off her mouth. At a time when normalcy was returning to Delhi, she should stop making these kind of provocative comments," said the minister of state for environment and forests.

Supriyo said if Banerjee at all had such suggestions, she could call on union home minister Amit Shah.

Participating in a political programme on Monday, Banerjee had said: "The way people have been killed in Delhi over the past few days, I think it's a planned genocide and later it has been portrayed as communal riots."

Blaming the BJP for the violence, she said instead of seeking forgiveness, it was trying to "capture new territories'.

Banerjee's comments came a day after Union Home Minister Amit Shah, addressing a rally at the Shahid Minar maidan here, accused Mamata of 'instigating' riots and torching of trains and railway stations during the violent anti-Citizenship (Amendment) Act protest last December.
