Kolkata, Oct 12 (ANI): Trinamool Congress (TMC) party blamed the Central government for the blast in West Bengal, saying the intrusion of members of extremist groups into the state led to the incident. Two suspected militants were killed and one sustained injuries in an explosion at a TMC leader's house in Burdwan district on October 2. TMC leader Partha Chatterjee said that the Central government is not serious and competent enough to depute border guards and that is why illegal migrants are intruding into West Bengal. He also said the wing of ruling BJP and Communist Party of India-Marxist (CPI-M) are disrupting the peaceful situation in the state to reap political benefits. Meanwhile, National Investigation Agency (NIA) is also assisting the state police in the case.
