 Russia carried out 465 chemical attacks on Ukraine since the full-scale invasion. From the beginning of the full-scale invasion, Russian terrorists have used chemical weapons 465 times to attack Ukraine according to the support force command of Ukraine. The defence forces have recorded 465 cases of the use of ammunition by the Russian Federation equipped with poisonous chemical substances. Of these, 81 cases occurred in December of the current year alone, the statement says. At the same time, the command notes that the dynamics of the use of such weapons by the occupiers are increasing. For example, on a single day, December the 19th, the Russians carried out 8 attacks using chemical substances. Most often, the enemy uses grenades such as K-51, RGR, and the handheld gas-grenade Drofa PM, which are dropped from drones. However, improvised explosive devices equipped with irritants are used. Artillery shelling with chemically hazardous substances is also carried out. For instance, on December the 14th, the use of a new type of special gas-grenade, RGVO, with an unknown chemical substance was discovered. It is noted that 28 cases of the use of dangerous chemical substances have been documented and sent for investigation as part of the criminal proceedings by the groups of radiation, chemical and biological reconnaissance from the military units of the support force command, together with security service of Ukraine.
