'If the (Indian) prime minister says something like this, we can't take it lightly,' Pakistan's Foreign Minister Shah Mehmood Qureshi told reporters on the sidelines of an official function in Islamabad.

'If there is such information with (India), share it with the government of Pakistan so that we can pre-empt such an act,' he said.

'In all sincerity, we would request India to share information they have and for our part we stand ready to cooperate fully in pre-empting any act of terror,' Pakistan's Foreign Office said.

The Indian envoy in Pakistan asserted that proof of this had already been shared.

India has already provided to Pakistan solid proof of possible terror attacks being staged on it from this country, Indian High Commissioner to Pakistan Sharat Sabharwal was quoted as saying.

'Terrorists living on Pakistani soil are posing a serious threat to India and it is the responsibility of the Pakistani government to eliminate it,' the Online news agency quoted Sabharwal as saying.

The terrorists who executed the 26/11 Mumbai carnage belonged to Pakistan and proof of this had been provided to Islamabad, which should take the necessary action in this regard, the envoy said.
