Estonia attributes Milrem Robotics arson to Russian security services

Estonia said on 29 September that Russian security services commissioned the August arson at a building used by Milrem Robotics in Tallinn. Prime Minister Kristen Michal said the attack was part of a campaign to intimidate Estonia and weaken its support for Ukraine. The Kremlin denied involvement. The allegation raises the significance of a fire that injured no one, but the criminal investigation is continuing and the cited public accounts do not disclose the evidence behind Estonia’s attribution.

Estonia’s Internal Security Service assessed the attack as deliberate and planned in advance, according to the Associated Press. The service said its method was consistent with other acts of sabotage in Europe that it has attributed to Russia, and assessed this attack as directly attributable to the Russian Federation. Those are the service’s conclusions; the publicly described findings do not independently establish who ordered the fire.

What happened in Tallinn

The fire broke out overnight on 15 August in a building used by Milrem Robotics on Betooni Street, in Tallinn’s Lasnamäe district. Emergency services brought it under control quickly. Estonian authorities said no lives were in danger, and the prosecutor’s office later said no one had been injured.

In an 18 August account, Estonia’s prosecutor general, Astrid Asi, said investigators had identified suspects and were examining possible motives, including whether the fire was an act of sabotage. The prosecutor’s office said the extent of the damage was still being assessed. It described the inquiry as being at an early stage and said it could not then share more specific information.

VDD said officers searched seven locations connected to the suspects, including homes and vehicles. They seized data-storage devices, whose contents the service said it was analysing, as well as objects that may have been used to set the building on fire. Seizing those items does not, by itself, establish who may have commissioned the attack.

Estonia’s government said Latvia handed all three suspects over on 17–18 September. It said the people believed to have directly carried out the arson were in custody and no longer posed a threat. Its account also said the investigation into the incident’s exact circumstances was continuing, although preliminary information gathered in the proceedings indicated that the attack had been commissioned.

Attribution and denial

Michal said in a public statement that the attack against Milrem Robotics had been ordered by Russian special services. He called it part of a wider effort to intimidate Estonia and weaken support for Ukraine. He said Estonia would respond with stronger domestic security, more support for Ukraine and greater pressure on Russia.

Kremlin spokesman Dmitry Peskov rejected Estonia’s accusation as unfounded and said Moscow would not take it seriously, according to the Associated Press. The agency also reported that Estonia’s foreign minister, Margus Tsahkna, said Russia’s chargé d’affaires in Tallinn was being summoned to the foreign ministry over the incident.

The new attribution is more definite than Estonia’s initial public account. In August, the prosecutor’s office described arson as a possibility and sabotage as a potential motive under investigation. On 29 September, Estonian officials publicly identified Russian security services as having commissioned the attack, while saying the inquiry itself was still open.

What remains unresolved

The Associated Press has reported that Milrem supplied THeMIS unmanned ground vehicles to Ukraine. That connection helps explain the attention to the company, but the cited accounts do not establish that its support for Ukraine motivated the fire. Nor do they establish the extent of damage or any effect on Milrem’s operations.

The cited public accounts do not set out the evidence or intelligence linking the alleged commissioners to Russian special services. They also do not establish the suspects’ identities, their specific alleged roles or any demonstrated link between them and Russian officials. Estonia’s attribution remains an official assessment disputed by Moscow while investigators continue their work.
