BJP's prime ministerial candidate Narendra Modi today sought answers from UPA citing an interview of former central Home Secretary Ram Pradhan which said he had told the then Home Minister about a local mole who allegedly helped carry out 26/11 attacks.

"Read former Union Home Secretary Ram Pradhanji's interview to Hindu. His revelations on 26/11 are shocking but not unexpected," Modi said in a series of tweets.

-- Told Home Minister (P Chidambaram) on local mole...suggested matter be pursued...don't know what happened to that'. Will UPA explain?" the Gujarat Chief Minister said in his tweet, seeking answers from the UPA government a day after the fifth anniversary of the worst terrorist attack on Mumbai, while quoting a sentence from the interview.

Pradhan, a former central Home Secretary, had led a two-member inquiry committee into the administration's response to 26/11 attacks.

Further quoting the interview, Modi tweeted, "...central agencies did not cooperate for their own reasons...no input from Central agencies despite repeated requests-Ram Pradhan Ji."
