Pakistan’s military has formally rejected the findings of a U.S. inquiry into last month’s NATO attack that killed 24 Pakistani soldiers along the Afghan border. The military on Monday said that it does not agree with several portions of the investigation report, calling them factually not correct.

Dismissing the findings, Pakistan’s military said the U.S. findings holding Pakistan partially responsible for the incident is unjustified and unacceptable. In the probe, U.S. defense officials blamed inadequate coordination by both Pakistani and U.S.-led forces for the November 26 attack. The U.S. military probe also found that U.S. forces acted in self-defense and with appropriate force after being fired upon.

The border attack brought U.S.-Pakistan relations to a new low point, with ties already strained over the covert U.S. raid that killed Osama bin Laden last year and a number of U.S. drone strikes targeting militants in Pakistan’s northwest.
