the use of chemical weapons in Syria by any parties in the conflict". In March 2014, the Commission published a report that stated that the chemical agents used in the Khan al-Assal chemical attack bore "the same unique hallmarks as those used in Al-Ghouta" in the August 2013 chemical attack. The report also indicated, based on "evidence available concerning the nature, quality and quantity of the agents used" that the perpetrators of the Al-Ghouta attack "likely had access to the chemical weapons stockpile of the Syrian military". In none of the incidents, however, was the commission's "evidentiary threshold" met in regards to identifying the perpetrators of the chemical attacks.

That was followed by various negative official responses, military and civilian, from the US and Canada. Del Ponte's office subsequently issued a statement dated four days later: "NATO is not under investigation by the Office of the Prosecutor of the ICTY. There is no formal inquiry into the actions of NATO during the conflict in Kosovo". Organ smuggling allegations In 2008, Del Ponte published a book The Hunt in which
