Estonia blames Russia for arson attack on defense company supplying Ukraine

Estonian authorities have formally accused Russian security services of commissioning an August 15, 2026, arson attack on Milrem Robotics, a Tallinn-based defense firm supplying unmanned ground vehicles to Ukraine. Three suspects arrested in Latvia have been extradited to Estonia. While the Kremlin dismissed the allegations as baseless, NATO and European leaders, including French President Emmanuel Macron, rallied behind Estonia, framing the incident as part of an escalating Russian campaign of sabotage across Europe.
