Russia's FSB detains a teenager suspected of planning the Tsaritsyno attack after the US tip-off.
Russia's domestic security service, the FSB, said on Saturday it had detained a Russian teenager suspected of planning a terrorist attack at the Tsaritsyno Museum Reserve in southern Moscow, hours after the US Embassy warned of a credible threat there.
The US Embassy in Moscow said it was aware of "a credible threat of a mass casualty event" at the museum reserve, at Dolskaya Ulitsa 1, and told American citizens to stay away from the area and avoid crowds, according to a statement on its website cited by The Independent.
The FSB said it had received the information through established channels with its American counterparts and thanked the US side for sharing it. "We have received information from US partners regarding plans for a terrorist attack in Moscow. We are taking appropriate action," the agency said, according to The Independent.
Russian police and emergency services evacuated staff and visitors from the museum grounds on Saturday afternoon, cutting short a concert under way at the site, The Independent reported. About 50 security officers were sent to cordon the former imperial estate, with patrol vehicles stationed around its perimeter.
The FSB said the detained teenager, a Russian citizen, had posted photographs of himself on TikTok in tactical clothing, a balaclava, cap and headphones, holding an object resembling an automatic weapon, including images taken at Tsaritsyno captioned "I found a place." A search of his belongings and devices turned up a subscription to a neo-Nazi Telegram channel and a large number of searches for past terrorist attacks and mass killings, the agency said.
Germany's embassy in Moscow separately warned its citizens to avoid the museum reserve, sending an alert through the foreign ministry's crisis-notification system, Novaya Gazeta Europe reported. The museum and park reopened to visitors as normal on 1 November, Euronews Albania reported. No casualties or attack took place, and officials have not said who the suspect was working with, if anyone.

Why it matters for Europe
The US has previously shared intelligence with Moscow about a planned attack: before the March 2024 Crocus City Hall attack, which Islamic State claimed and which killed around 145 people, a similar US warning went largely unheeded. This time, the tip led to an evacuation and an arrest within hours. The episode shows that European citizens living or travelling in Russia can be warned of threats by their own embassies, as Germany's did alongside the US.
