ISLAMABAD (AP) - The U.S. ambassador to Pakistan has apologized for a recent helicopter attack that killed Pakistani soldiers near the Afghan border.
Anne Patterson said in a statement Wednesday that a joint investigation has established that U.S. helicopters mistook the soldiers for insurgents they had been pursuing.
Pakistan has said the attack on Sept. 30 killed three members of Pakistan's Frontier Corps and wounded three others.
But Patterson's statement said two soldiers were killed and four were injured.
Following the attack, Pakistan shut down a key border crossing used to ship a large proportion of goods to NATO soldiers in Afghanistan.
