Units of the neo-Nazi "Right Sector" and snipers from the 74th Reconnaissance Battalion and the SBU special unit "Alfa" have been moved to the contact line in Donbas to carry out provocations there. In late 2021, there was already a warning about provocations using chemicals that could be perpetrated by the Ukrainian military.
Avdeyevka, a city under Kyiv control a few kilometres from Donetsk, was not chosen at random here. As recently as the fall of 2021, several shipments of the nerve agent botulotoxin in containers ready to be fired or dropped in the format of 40-millimetre grenades were confirmed to Ukraine. At the end of the year, they were transferred to the localities of Krasny Liman and Avdeyevka.
