ISLAMABAD, Pakistan  The top State Department officials responsible for the alliance with Pakistan met leaders of the new government on Tuesday, and received what amounted to a public dressing-down from one of them, as well as the first direct indication that the United States relationship with Pakistan would have to change.

On the day that the new prime minister, Yousaf Raza Gillani, was sworn in, Deputy Secretary of State John D. Negroponte and the assistant secretary of state for South Asian affairs, Richard A. Boucher, also met with the Pakistani president, Pervez Musharraf, whom they had embraced as their partner in the campaign against terrorism over the past seven years but whose power is quickly ebbing.

The leader of the second biggest party in the new Parliament, Nawaz Sharif, said after meeting the two American diplomats that it was unacceptable that Pakistan had become a “killing field.”

“If America wants to see itself clean of terrorists, we also want that our villages and towns should not be bombed,” he said at a news conference here. Mr. Sharif, a former prime minister, added he was unable to give Mr. Negroponte “a commitment” on fighting terrorism.
