NATO attack in Pakistan: NATO forces in Afghanistan attack a Pakistani check post in a friendly fire incident, killing 24 soldiers and wounding 13 others.

The 2011 NATO attack in Pakistan was a border skirmish that occurred when United States-led NATO forces engaged Pakistani security forces at two Pakistani military checkposts along the Afghanistan–Pakistan border on 26 November 2011, with both sides later claiming that the other had fired first. Two NATO Apache helicopters, an AC-130 gunship and two F-15E Strike Eagle fighter jets entered as little as 200 metres (660 ft) to up to 2.5 kilometres (1.6 mi) into the Pakistani border area of Salala at 2 a.m. local time. They came from across the border in Afghanistan and opened or returned fire at two Pakistani border patrol check-posts, killing 28 Pakistani soldiers and wounding 12 others. This attack resulted in deterioration of relations between Pakistan and the United States. The Pakistani public reacted with protests all over the country and the government took measures adversely affecting the American exit strategy from Afghanistan, including the evacuation of Shamsi Airfield and closure of the NATO supply line in Pakistan. Pakistan also rejected a U.S. offer of compensation for the killing of its soldiers in the NATO attack.
