Pakistan's Inter Services Intelligence has rejected the findings of a US-NATO probe into the November 26 airstrike that had killed 24 soldiers.

An Inter- services Public Relations (ISPR) statement described the report as biased and lacking in key facts, The News reports.

The ISPR would give a formal reply to the report after receiving its details, the statement added.

The statement came after the United States announced the findings of a military probe into the incident, which suggested that Pakistani troops fired the first shot on the Afghan-U.S. commando team.

But the report admitted that the U.S. made several blunders during the airstrike, including misunderstanding a radio transmission and believing there were no Pakistani forces in the area.

The US troops passed incorrect information to the Pakistan soldiers regarding the location of the raid, the report added.
