Deputy Protection Minister Hanna Maliar mentioned it was doable that phosphorus munitions — which trigger horrendous burns however should not categorized as chemical weapons — had been used.
Now the query is how one can set up the reality amid the fog of warfare that has descended over a metropolis nonetheless beneath assault from Russian forces. A transparent reply is unlikely to emerge anytime quickly.
The worldwide chemical weapons watchdog mentioned Tuesday that it's “involved by the current unconfirmed report of chemical weapons use in Mariupol” and is carefully monitoring the state of affairs in Ukraine. Each Russia and Ukraine belong to the 193-member Group for the Prohibition of Chemical Weapons.
The OPCW, which was awarded the Nobel Peace Prize in 2013, says that it “stays prepared to help any State Celebration upon its request, in case of use or risk of use of chemical weapons.”

Meaning taking soil samples and testing them for traces of doable chemical weapons or different munitions. Samples of blood and urine from victims who have been uncovered to the munition would even be examined.
Then investigators would search to interview witnesses and survivors, to construct an image of what they skilled, and the physicians who handled them. In previous investigations, specialists have studied fuel dispersion fashions and topographic charts and checked out digital photos. The OPCW has expertise constructing such investigations in Syria, the place its specialists have confirmed using chemical weapons on a number of events.
