Suspecting the role of home grown sleeper modules of terror groups in Mahabodhi temple blasts, BJP today lashed out at the UPA government for "totally failing" in tackling terror and accused it of linking the nation's security with "vote bank politics".

BJP President Rajnath Singh, who visited Bodhgaya along with senior leaders Arun Jaitley and Ravishankar Prasad, demanded a thorough probe into the incident and urged the Centre to show "firm will" to fight the menace of terror.

Both Singh and Jaitley also alluded to the Ishrat Jahan encounter case, which has led to some sort of a CBI-versus IB face off and triggered speculation that probe findings in the "fake encounter" case could reach to Narendra Modi's door.
