NEW DELHI Pakistan President Asif Ali Zardari warned India Saturday against any `over-reaction` after the militant attacks in Mumbai and vowed the `strictest` action if Pakistani involvement was proved.

`Whoever is responsible for the brutal and crude act against the Indian people and India are looking for reaction,` Zardari said in an interview with Indian CNN-IBN television.

`We have to rise above them and make sure ourselves, yourself and world community guard against over-reaction,` he said according to an interview transcript issued by the Press Trust of India.

The Indian government has blamed `elements in Pakistan` for the attack by Islamist militants against multiple targets in Mumbai that left nearly 200 people dead.

Zardari promised that he would take immediate and strong measures if proof was provided of Pakistani involvement.

`Let me assure you that if any evidence points to any individual or any group in this part of the world, I shall take the strictest of action in the light of this evidence and in front of the world,` he said.

Zardari argued that reducing the Mumbai attacks to an India-Pakistan problem was counter-productive.

`This is a world threat and all the more reason we have to stand up against this threat together,` he said.
