The US-led coalition, the United Nations and Afghan officials will launch a joint probe into a deadly raid in western Afghanistan, to a top NATO official said Saturday. Brig. Gen. Richard Blanchette, the chief spokesman for the NATO-led force in Afghanistan, said the investigation would aim to clarify what happened during the Aug. 22 raid in the village of Azizabad in the western Herat province. The Afghan government and UN say some 90 civilians were killed. The US-led coalition maintains that 25 militants and five civilians died in the raid. Dan McNorton, a UN spokesman in Kabul, confirmed the decision to launch the joint probe.
