The Russian Defense Ministry has frequently warned that Ukrainian military and nationalist groups are planning grave provocations to blame on Moscow. So far, the West has ignored Russia's worries and warnings.

According to the Russian Ambassador to the United States Anatoly Antonov, the allegations are another US attempt to demonize Russia.

The Russian embassy's Telegram channel quoted the official detailing how "such claims are worth a penny. The US official, as always, did not bother to provide any evidence. This is another attempt to demonize our country."

Antonov added that Russia, unlike the US, "eliminated all available stocks of chemical warfare agents in 2017. This fact has been documented by the OPCW. It is pointless to argue with this fact."

Two days ago, the Russian Ministry of Defense stated that preparations were underway for a provocation in Kharkov, using 80 tons of ammonia to accuse Russia of conducting a chemical attack.
