Now, the Pakistani official has said that the country will be cutting all supply lines to U.S. and NATO troops in Afghanistan.

From the New York Times:

“Business as usual will not be there,” Mr. Gilani said of the already frayed relationship with the United States. “We have to have something bigger that satisfies my nation and entire country.”

Mr. Gilani made his remarks in an interview on CNN, excerpts of which were prominently broadcast on Pakistani networks.

The Pakistani military spokesman, Maj. Gen. Athar Abbas, rejected an account of the attack laid out by diplomats in Afghanistan and American officials in Washington.

Pakistani officials say there was no military activity going on at the time, and that NATO forces had grid coordinates of all military posts. The U.S. military has not been able to give a concrete response, except note that a "tactical situation" began to unfold on the ground.

From the BBC:

Late on Saturday, US Secretary of Defense Leon Panetta and Secretary of State Hillary Clinton released a statement saying they offered their "deepest condolences for the loss of life and support fully Nato's intention to investigate immediately".

They stressed the "importance of the US-Pakistani partnership, which serves the mutual interests of our people" and pledged to remain in close contact with their Pakistani counterparts, the AFP news agency quoted the statement as saying.

Pakistan's government has now summoned the U.S. Ambassador and asked the country to vacate all forces from the Shamsi air base, which the U.S. has used to launch drones for the past several years.
