FSB Detains Teen After U.S. Alert

Russian security officials detained a teenager following an intelligence briefing from the United States that warned of a planned terrorist attack in Moscow. The Federal Security Service stated on Sunday that it verified the data provided through official partner channels and acted on the information. The arrest of the minor followed a series of operations launched after the alert was received.

The U.S. Embassy in Moscow confirmed it was aware of a credible threat regarding a mass casualty event. The warning focused on Saturday at the Tsaritsyno Museum Reserve, a palace and park complex located south of the capital. American officials said they were coordinating directly with Russian law enforcement to manage the situation.

The FSB described the detained individual as a Russian minor who had posted videos on TikTok. In the clips, the teen wore tactical gear, including a balaclava, protective eyewear, and headphones, while holding an object resembling an automatic weapon. A search of the suspect's devices revealed a subscription to a neo-Nazi channel on Telegram. The agency also found numerous search queries related to past terrorist attacks and mass shootings.

Russian media reported that the Tsaritsyno venue was temporarily closed on Saturday. Access to the park was restricted by law enforcement. An organ concert at the location was cut short with about ten minutes remaining in the program, prompting an evacuation. A separate concert dedicated to North Caucasian folk traditions was also canceled.

This incident follows a similar warning in March 2024, when the U.S. Embassy advised Americans of imminent extremist plans in Moscow. Days after that alert, gunmen attacked the Crocus City Hall concert venue outside the city. The attack resulted in the death of more than 140 people, marking one of the deadliest terrorist incidents in recent Russian history.
