Russian authorities detained a teenager suspected of preparing an attack at Moscow’s Tsaritsyno Museum Reserve after a warning from the United States, Al Jazeera reported on November 1, citing Interfax’s account of statements by Russia’s Federal Security Service.
The US Embassy in Moscow had issued a security alert a day earlier, warning of a credible threat that could cause mass casualties at the palace and park complex. It advised people to stay away and said American officials were coordinating a response with Russian authorities. The park temporarily closed following the alert.
According to the FSB, the unidentified suspect is a Russian citizen who posted TikTok photos wearing tactical clothing and a balaclava while holding an object resembling an automatic weapon. The teenager also allegedly shared pictures from Tsaritsyno with a caption suggesting it had been selected as a location.
The FSB said a home search found clothing and accessories matching those in the images. It also alleged that the teenager’s phone contained searches concerning terrorist attacks and mass killings, along with a subscription to a neo-Nazi Telegram channel. Those claims were attributed to the security service, not presented as court findings.
The FSB thanked the United States for the information and said Russia’s Investigative Committee was considering legal action against the suspect. The exchange occurred amid longstanding tensions between Washington and Moscow over Russia’s war in Ukraine.
