Médecins Sans Frontières called for an independent inquiry of the air attack on the hospital, accusing the United States of committing a "war crime" and calling an internal U.S. investigation insufficient.[1][60] The call for an independent investigation was supported by The Lancet,[61] and the UN High Commissioner for Human Rights, Zeid Ra'ad Al Hussein.[62] MSF suggested that the International Humanitarian Fact-Finding Commission, which is based in Bern, should undertake this work.[63]
