The UN investigation into the chemical attacks in Ghouta was published on 16 September. The report stated that "the environmental, chemical and medical samples, we have collected, provide clear and convincing evidence that surface-to-surface rockets containing the nerve agent sarin were used in Ein Tarma, Moadamiyah and Zamalka in the Ghouta area of Damascus."[1] The inspectors were able to identify several surface-to-surface rockets at the affected sites as 140mm BM-14 rockets originally manufactured in Russia and 330mm rockets probably manufactured in Syria.[20] U.N. Secretary General Ban Ki-moon called the findings "beyond doubt and beyond the pale," and clear evidence of a war crime. "The results are overwhelming and indisputable ... A majority of the rockets or rocket fragments recovered were found to be carrying sarin."[21] The report, which was "careful not to blame either side," said that during the mission's work in the rebel controlled Zamalka and Ein Tarma neighborhoods, "individuals arrived carrying other suspected munitions indicating that such potential evidence is being moved and possibly manipulated."[22] The areas were under rebel control, but the report did not elaborate on who the individuals were.[23] The UN investigators were accompanied by a rebel leader:
A leader of the local opposition forces [...] was identified and requested to take 'custody' of the Mission [...] to ensure the security and movement of the Mission, to facilitate the [sic] access to the most critical cases/witnesses to be interviewed and sampled by the Mission and to control patients and crowd in order for the Mission to focus on its main activities.[1]
