ISLAMABAD, Pakistan - Pakistan says it has protested to NATO over an air strike that it says killed 11 of its soldiers in a base on the Afghan border.

Foreign Minister Shah Mehmood Qureshi's office said he conveyed the protest to NATO Secretary General Jaap de Hoop Scheffer during a conference on Afghan reconstruction in Paris.

A ministry statement released late Thursday said Qureshi described the strike as `unprovoked and senseless' and a `blatant and wilful negation of the sacrifices Pakistan has made in the war against terrorism.'

The ministry said that de Hoop Scheffer expressed regret.

U.S. officials say coalition forces in Afghanistan bombed militants in the same area Tuesday night and are investigating whether any Pakistanis were hit.
