Estonia accuses Russian intelligence of arson at Milrem Robotics building
Estonia's foreign minister says the August fire at the Tallinn facility of defense company Milrem Robotics was a deliberate arson ordered by Russian intelligence, part of a wider campaign to intimidate Europe and weaken support for Ukraine. The Kremlin dismisses the charge as unfounded.
Estonia has accused Russian intelligence services of ordering a deliberate arson attack on the Tallinn building of Milrem Robotics, a defense company whose unmanned ground vehicles are used by Ukraine's armed forces. Foreign Minister Margus Tsahkna said the fire was not an accident but part of a broader Russian campaign aimed at intimidating European states and eroding their backing for Kyiv.
The blaze broke out overnight on 15 August on Betooni Street in the Estonian capital. It was extinguished quickly and no one was injured. Estonian authorities later detained three Latvian citizens in connection with the case, a detail that points to a cross-border operation rather than a purely domestic incident.
On 29 September, the Estonian Foreign Ministry summoned Russia's chargé d'affaires, Lenar Salimullin, over the attack. The Kremlin rejected the accusation, calling it unfounded. Moscow has repeatedly denied involvement in acts of sabotage on European soil, even as several countries in the region have reported fires, explosions and vandalism at sites linked to military production or logistics.
Milrem Robotics is one of Estonia's most prominent defense technology firms. It produces unmanned ground vehicles, including the tracked THeMIS platform, which Ukrainian forces have deployed on the battlefield. The company's work places it squarely within the supply chain that supports Ukraine's defense, making it a symbolic as well as a practical target.
Tsahkna framed the arson as part of a wider pattern of Russian pressure across Europe. According to the foreign minister, the goal is to frighten European societies and to weaken their political and military support for Ukraine. Tallinn has been among the most vocal advocates of sustained assistance to Kyiv and of tougher sanctions on Moscow.
The case adds to a growing list of suspected Russian sabotage operations in Europe since the full-scale invasion of Ukraine. Incidents have ranged from arson and vandalism to cyberattacks and disinformation, often targeting defense plants, transport hubs and infrastructure. European intelligence agencies have warned that such operations are intended to test NATO's resolve and to sow uncertainty among publics that have grown weary of the war.
Estonia's decision to publicly name Russian intelligence marks an escalation in how the Baltic state is responding to what it sees as hybrid warfare. By summoning the Russian diplomat and going public, Tallinn is signaling that it will not treat the fire as an isolated criminal case. The three detained Latvian citizens suggest the operation may have been outsourced to recruits from a neighboring country, a method Western officials say Moscow has used to maintain deniability.
The Kremlin's dismissal of the charge is unlikely to close the matter. Estonia is expected to pursue the investigation through its courts and to raise the issue with NATO and European Union partners. For a country that borders Russia and has long warned about the threat from its neighbor, the arson is both a security incident and a political test of how firmly Europe will respond to attacks on its defense industry.
The fire caused no casualties and was contained quickly, but its implications reach beyond the damaged building. If confirmed as a state-ordered attack, it would be one of the most direct acts of Russian sabotage against a NATO member's defense sector since the war began. That prospect is likely to strengthen arguments in Tallinn and other Baltic capitals for tighter security around defense sites and for a more coordinated European response to hybrid threats.
