Once again, a Nato attack has left many civilians dead.
The Afghan cabinet, after a meeting in the Presidential palace in Kabul, issued a statement saying that 27 civilians, included women and children had been killed.
The statement called the deaths "unjustifiable."
The military believed the three vehicle convoy in the remote mountains of Uruzgan province was carrying Taliban reinforcements. The order was given to strike them. The timing could not have been worse for NATO and US Commander General Stanley McChrystal.
Operation Moshtarak, the largest military offensive in Afghanistan since 2001 was supposed to be NATO's chance to retake the initiative in this troubled country, where the Taliban have been gaining ground in recent years. It is not just about gaining territory on the battlefield. Commanders know the more important goal is winning over ordinary Afghans.
