ISLAMABAD, Pakistan — Pakistan reiterated Sunday that it will not let American forces hunt Al Qaeda and Taliban militants on its soil, after a news report said Washington was considering expanding U.S. military and intelligence operations into Pakistan's tribal regions.

The Foreign Ministry dismissed as "speculative" a story in the New York Times on Sunday saying U.S. President Bush's top security officials discussed a proposal Friday to deploy American troops to pursue militants along the Pakistan-Afghan border.

"We are very clear. Nobody is going to be allowed to do anything here," said Maj. Gen. Waheed Arshad, the army's top spokesman.

"The government has said it so many times," Arshad said. "No foreign forces will be allowed to operate inside Pakistan."

In Afghanistan, President Hamid Karzai's spokesman did not immediately return a call seeking comment.
