Ukrainian authorities have detained a 17-year-old girl on suspicion of poisoning soldiers on instructions from Russian services. Two soldiers who received the poison capsules have died. According to the account released with the announcement, the recipients did not know that the capsules contained a lethal dose of methadone. The case is being treated as an operation run by Russian intelligence to eliminate Ukrainian military personnel through unwitting intermediaries. Investigators are working to establish how the teenager was recruited and how the scheme was organised. The detention adds to a series of reported sabotage and poisoning attempts linked to Russian services since the full-scale invasion began.
