After the 2016 Nagorno-Karabakh conflict over disputed territory of Nagorno-Karabakh Azerbaijani Ministry of Foreign Affairs stated that on 10 May of that year the Armenian military had fired 122mm white phosphorus artillery munitions against Azerbaijani territory. On May 11, Azerbaijan's Defense Ministry jointly with the Foreign Ministry invited military attaches from 13 countries to visit the territory in the Askipara village where the Defense Ministry sais they had found a white phosphorus munition fired by Armenian forces. The use of phosphorus munition by the Armenian military was also reported by Al Jazeera. The Azerbaijani Military Prosecutor's Office initiated a criminal case upon the finding. NKR foreign ministry and Armenia defence ministry dismiss it as a falsification and distortion of the reality. Armenian media sources disclaimed it as a staged operation by Azerbaijan, citing absence of evidence of the presence of a shell or of a shell being used by Armenians, adding that this was a non-story as there was no evidence of any use.
