An adviser to Ukraine’s interior ministry said in response that the alleged poisoning could have been caused by Russian forces eating expired canned meat.
The Russian defence ministry said a number of Russian servicemen had been taken to a military hospital with signs of serious poisoning on Jul 31. Tests showed a toxic substance, botulinum toxin type B, in their bodies, it said.
“On the fact of chemical terrorism sanctioned by the (Ukrainian President Volodymyr) Zelensky regime, Russia is preparing supporting evidence with the results of all the analyses,” the ministry said in a statement.
It did not say how many servicemen had suffered or what their condition was now. It did not say what the “supporting evidence” was.
Botulinum toxin type B is a neurotoxin that can cause botulism when ingested in previously contaminated food products, but it can also have medical uses.
Ukraine’s defence ministry did not immediately respond to a Reuters request for comment, but interior ministry adviser Anton Gerashchenko commented on the Russian allegation on the Telegram messaging app.
Ukraine and Western countries view it as an unprovoked war of conquest aimed at wiping out Ukraine’s national identity.
