 At least four people voicing criticism against Moscow have experienced possible poisoning over the past two years. Mostly during the war with Ukraine, Russian language Agnestvo news website has reported. During this period, there have also been cases of unknown individuals with ties to Russian special services breaking into people's houses. Agnestvo has also reported possible poisoning of head of the Free Russia Foundation Natalia Arno Budiva in early May this year. Thus, while holding meetings in Prague over the political situation in Russia, Arno felt numbness and pain in various parts of her body. According to reports, shortly before the onset of symptoms, Arno realized that the door to her hotel room in Prague was open and that the room smelled like cheap perfume. Moreover, Agnestvo has been informed by two separate sources that a few months prior to Russia's invasion of Ukraine, former US Ambassador to Ukraine and Uzbekistan John Herbst had symptoms of poisoning. He is currently the Director-General of the Atlantic Council's Eurasia Center. It should be noted that Russia's major opposition leader, Alexei Navalny, was also poisoned in a mysterious way in the past.
