"There is no doubt that the blasts were an attempt to disrupt the BJP rally. In fact, it's a direct attack on Modiji. We don't know who are behind this attack, but both the centre and Bihar governments are answerable," Bharatiya Janata Party (BJP) spokesperson Meenakshi Lekhi told reporters here.
Addressing a party event here, Lekhi called the Congress-led United Progressive Alliance (UPA) central government "worthless" for the seven low-intensity blasts which killed five people.
Lekhi also attacked Congress vice president Rahul Gandhi for his remarks that Pakistan's Inter Services Intelligence contacted Muslim youths affected by the Muzaffarnagar communal violence in Uttar Pradesh.
"Who is he to be briefed by the intelligence agencies....if he is correct, what has the centre done in this regard...why does he keep raising the issue of assassination of his grandmother (Indira Gandhi) and father (Rajiv Gandhi) who were killed because of their faulty politics?" she asked.
Without naming the Mamata Banerjee-led Trinamool Congress government in West Bengal, she accused it of communally polarising the state.
"Bengal traditionally has been known for its communal harmony. But we can see attempts are now being made to communally polarise the state. The signs are not good," added Lekhi.
