Estonian authorities are investigating a suspected arson attack possibly linked to Russia in a Tallinn facility used by defense manufacturer Milrem Robotics.

Emergency crews responded to the fire in the Lasnamäe district after a local resident reported suspicious activity.

No injuries were reported, and officials are now assessing the extent of the damage.

Law enforcement agencies identified suspects residing in Latvia, while prosecutors have requested their detention.

Estonian Prosecutor General Astrid Asi confirmed investigators are weighing potential motives, including an attempted sabotage.

“If the purpose of this act was to scare Estonia, to make our people fight among themselves, or to make us give up supporting Ukraine, then it will not succeed,” Estonian Prime Minister Kristen Michal stated.

“Estonia does not allow itself to be threatened or influenced. We stand by our decisions and will continue to support Ukraine.”

Negligible Effect

Milrem Robotics produces unmanned ground vehicles deployed in Ukraine. The company, majority-owned by the UAE’s state enterprise EDGE Group, plans to have more than 200 robotic systems deployed in Ukraine by the end of this year.

Milrem CEO Kuldar Väärsi confirmed the incident will not impact production, supply chains, or distributions.

“Nothing really disturbs our deliveries this year or next year,” Väärsi told Reuters.

Meanwhile, Estonian Internal Security Service Director General Margo Palloson urged defense firms to strengthen physical and digital protection, noting that Moscow “poses a long-term existential threat” to the Baltic state.
