Mr Roy himself stopped short of naming any political party as he told the Press Trust of India: "Forces currently attacking the ruling Trinamool Congress all over Bengal are behind the attack. Today is October 2, the birthday of Mahatma Gandhi. We all know which group was involved in Gandhiji's killing. I will not be surprised if that same group was involved in this blast." He alleged that the plan was to create panic.

But another Trinamool leader, Mr Purnendu Bose, who is the local MLA told ANI he suspected an RSS hand behind the incident. That claim. Immediately sparked an angry coutburst from.

The ruling Trinamool and the Left have traded charges of crude bomb attacks and other violence in the past.

Prime Minister Narendra Modi's BJP, which has been making inroads in the state over the past few years, has also sparred with Chief Minister Mamata Banerjee's party over political violence.

The two parties blamed each other soon after today's explosion.
