Russia arrests minor after US warns of planned attack on Moscow

Russian police have detained a minor on suspicion of planning an attack on Moscow, following a tip-off from the United States, according to reports on Sunday. The U.S. Embassy in Moscow had previously warned of a credible threat of a mass casualty event at the Tsaritsyno Museum Reserve in the city, though they did not specify the perpetrators.

The Russian Federal Security Service (FSB) confirmed the arrest of an unidentified male, believed to be a Russian citizen, who had shared images of himself posing with what appeared to be an automatic weapon, along with a caption indicating his presence at the museum. The FSB praised the U.S. for the information provided. The Tsaritsyno museum, a historic imperial estate, was closed to the public on Saturday, with access limited to individuals leaving the grounds.

This incident follows previous U.S. warnings of planned attacks on Russia, including a March 2024 incident involving the ISIS-K group in a Moscow concert hall that resulted in over 100 deaths. Relations between Russia and the U.S. have recently improved, despite ongoing tensions with Kyiv over a US-Russia diesel deal.
