US-led coalition forces have released a video shot from a surveillance drone showing a controversial clash on the Afghan-Pakistan border. Pakistan claims the engagement led to an airstrike that killed 11 of its troops, but the coalition says the footage proves that US and Afghan forces were simply returning fire after being attacked, the AP reports.
"Every indication we have is that this was a legitimate strike against forces that had attacked members of the coalition," says the Defense Department's press secretary. The incident has shaken the already fragile partnership between the US and Pakistan in the battle against Taliban and al-Qaeda militants. (More Pakistan stories.)
