Rejecting India's demand to extradite the perpetrators of the Mumbai terror attacks to the country, Pakistan has said such a move will be "harmful" for it as there was no extradition treaty between the two neighbours.

"There is no extradition treaty between India and Pakistan. We are keen on rebuilding our internal institutions. So if we engage in these issues, it will be harmful for Pakistan," Foreign Minister Shah Mehmood Qureshi told Geo TV.
