ISLAMABAD, Feb 6: Pakistan on Friday dismissed as unwarranted a statement by Indian Foreign Minister Yashwant Sinha that the disclosure by Dr Abdul Qadeer Khan on leaking secrets be debated by the International Atomic Energy Agency.

"The investigations in Pakistan are an internal matter," foreign office spokesman Masood Khan said. "The buck stops here in Pakistan. The matter won't be debated elsewhere," he told AFP.

"Pakistan is already cooperating with the IAEA, therefore, Mr Sinha's advice in this regard is gratuitous." However, he said: "We do not disagree with Mr Sinha that all nuclear-capable states, including India, should behave in a responsible manner."
