"It is the most unthinkable accusation that anybody can make against India. It is a falsehood which is being spread. We deny any involvement in any blast, anywhere," Krishna told reporters.
Refuting the allegation, Krishna said that such remarks were the result of Pakistan's selective approach against terror.
"I think all these issues of blasts arise out of our attitude towards terror."
"When we take a firm stand against terror, not on a selective basis but across the board, then I am sure that Pakistan will be happier and India will be peaceful," Krishna said.
The external affairs minister added that India wants the 'best of relations and a stable Pakistan.'
Earlier, Pakistan interior minister Rehman Malik alleged that India was behind the suicide attack on Monday, Mar 8 at a building in Lahore, where main terror suspects were being interrogated by the police.
Meanwhile, official sources said that the allegations were baseless, adding that this was not the first time Pakistan has levelled such charges against India.
"No evidence has been shared with us. This is whole fabrication by that side. And they will continue doing it," the sources said.
