Pakistan's military has condemned an air strike by Afghanistan-based US forces that killed 11 of its troops as a "cowardly attack".
The incident happened inside Pakistan, near the border with Afghanistan, as US-led forces tackled pro-Taleban militants.
The US military confirmed it had used artillery and air strikes after coming under fire from "anti-Afghan" forces.
It comes amid rising tensions between the US and Pakistan militaries.
The soldiers' deaths occurred overnight at a border post in the mountainous Gora Prai region in Mohmand, one of Pakistan's tribal areas, across the border from Afghanistan's Kunar province.
In a statement, the Pakistani military quoted a spokesman who condemned "this completely unprovoked and cowardly act".
The spokesman said the incident "hit at the very basis of co-operation and sacrifice with which Pakistani soldiers are supporting the coalition in the war against terror" and added that the army had launched a "strong protest".
