A/HRC/25/59 and has judged the information and evidence he has seen to be sufficient to cross the threshold identified in his interim report as imposing a duty on the relevant States to provide a public explanation of the circumstances and the justification for the use of deadly force. 36. In the opinion of the Special Rapporteur, the States responsible are under a present and continuing obligation to make public, in as much detail as possible, and subject only to such redactions as are strictly necessary to meet legitimate national security concerns, the results of any fact-finding investigations that have been conducted into the incidents identified in the present section of the report. If no fact-finding investigation has so far taken place, the Special Rapporteur considers that the States concerned are under an obligation to indicate this publicly, and provide an explanation. 37. By way of illustration, the Special Rapporteur draws attention to the one instance in which the United States has previously made public significant parts of an investigation report into a strike in which civilian casualties were sustained in Afghanistan. On 21 February 2010, precision-guided munitions were discharged from a United States military helicopter aimed at three pick-up trucks travelling near Khotal Chowzar, a mountain pass that connects Daikundi with Oruzgan. The attack occurred 12 km from the village of Khod in the Shahidi Hassas district. Remotely piloted aircraft under the control of the United States were involved in assessing and determining the target of the operation. Up to 23 civilians were reportedly killed and 12 civilians were injured. The victims included eight men, one woman and three children under the age of 14. The findings of an investigation conducted by ISAF were partially declassified. The investigation concluded that the Predator drone crew involved had provided misleading situational information, that there was evidence of inaccurate and unprofessional reporting, and a propensity to “kinetic activity” (the discharge of precision-guided munitions). It recommended administrative and disciplinary sanctions.17 The publication of the investigation report is a model of accountability and transparency and sets a benchmark to be followed in other cases. In the opinion of the Special Rapporteur, the States implicated in the incidents set out below are under a duty to release the substance of all investigation reports in a level of detail comparable to that adopted in the case in question. 38. The Special Rapporteur therefore calls on relevant States to respond to the allegations set out below. He has written separately to them inviting their comments. Any responses that are received will, subject to the consent of the State concerned, be posted on the official web page of the mandate. Afghanistan 39. On 25 March 2011, precision-guided munitions were discharged at two vehicles travelling in the Now Zad district of Helmand province. Both vehicles were destroyed; six people were killed and two injured. Remotely piloted aircraft under the control of ISAF (United Kingdom) were involved in the operation. The United Kingdom has confirmed that, in addition to killing two men believed to be combatants (who were the targets of the attack), the operation resulted in the deaths of four non-combatants and the infliction of serious injuries on two further non-combatants. Contemporaneous reports suggest that the two identified targets were travelling in the first vehicle, and that the dead included two women and two children who were travelling in the following vehicle. The incident was investigated by the Joint Incident Assessment Team at ISAF, which concluded that the operation had been directed at two pick-up trucks believed to be carrying explosives and 17 10 Memorandum for Commander, United States Forces – Afghanistan, 13 April 2010, executive summary for AR-15-6 investigation, 21 February 2010, air-to-ground engagement in the vicinity of Shahidi Hassas, Oruzgan.
