Russia's Federal Security Service (FSB) announced that it has foiled a terrorist attack planned by Ukraine's Security Service (SBU) against a senior law enforcement official in Moscow, according to TASS. The agency said the attack was to be carried out using an improvised explosive device placed in an electric scooter and detonated remotely while the official visited a business center.

Coverage comparison

The details of the operation have been reported exclusively through TASS, which carried several statements from the FSB's press office. All three reports come from the Russian state news agency and present the information without visible variation in tone or content. The first and third reports, both dated April 3, describe the discovery of the device and the initial response. A later report from April 14 provides additional information about the detention of three individuals allegedly involved in the plot, offering more granular details about their roles and the device's construction.

Because TASS is a state-affiliated outlet, its reporting reflects official Russian government positions. Independent verification of the claims has not yet been possible, and no other international news agency has reported on this story in the provided material.

Key claims

The FSB stated that an electric scooter was found parked near the entrance to a business center in Moscow, with a powerful improvised explosive device in its trunk. The agency alleged that the SBU intended to detonate the bomb remotely during the target's visit to that location, according to TASS. The device, as described by the FSB and reported by TASS, consisted of a signal receiver with a power unit, a charge with pre-made impact elements, and an electronic relay with a power source. The FSB also said the IED contained 5 kilograms of plastic explosive with shrapnel and was intended to be triggered via a 'smart home' Wi-Fi relay and a 4G modem.

The FSB said that detonation of the device "could have led to a large number of civilian casualties." Footage released by the agency is said to show the device being neutralized at night, with a robot used to remove the explosive from the scooter's trunk.

According to TASS, three individuals were detained: a Ukrainian citizen born in 1980, a Moldovan citizen born in 1991, and a Russian citizen born in 2009. The FSB identified the Ukrainian as a serviceman in the Ukrainian armed forces who had fought against Russian forces in the Donetsk People's Republic, Zaporozhye, and Sumy regions. The agency claimed that in March of the previous year, he was recruited by the SBU and sent to Moscow to conduct reconnaissance and carry out an assassination of a military serviceman. On his handler's command, he allegedly removed bomb components from a cache, assembled the IED, and placed it in the scooter.

The Moldovan citizen was said to have been recruited in December in Chisinau and tasked with scouting the attack targets, renting a car, and organizing a live broadcast of the scene. The Russian citizen allegedly conducted video surveillance of the area for a monetary reward from the SBU, sending footage to his handler to help determine the parking location of the scooter.

The FSB has opened a criminal case under Article 1 of the Russian Criminal Code, which covers illegal handling of explosives, with further qualification under preparations for a terrorist attack (Articles 30 and 205). A search for others involved is reportedly underway.

What was claimed, and who backed it

AI-extracted; can misattribute a claim — see Methodology.

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status is Contested when two claims on this page negate each other; otherwise it counts the distinct outlets we found asserting it — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
