On 7 October 2015, President Barack Obama issued an apology and announced the United States would be making condolence payments of $6,000 to the families of those killed in the airstrike.[15][16][17] Three investigations of the incident were conducted by NATO, a joint United States-Afghan group, and the United States Department of Defense. The Department of Defense released its findings on 29 April 2016. MSF has called for an international and independent probe, saying the armed forces who carried out the airstrike cannot conduct an impartial investigation of their own actions.[17]
