Estonia weighs closing its three border crossings with Russia; Foreign Ministry sets Dec. 1
Key Facts
Estonia is considering closing its land crossings with Russia after the prime minister asked officials to prepare possible steps following an attempted act of sabotage targeting a building belonging to defense company Threod Systems. The interior minister said the government would discuss in the coming days whether the closure should be temporary or indefinite, while the Foreign Ministry said the closure date would be Dec. 1. That means the date has been announced, while the closure’s duration and nature remain under government consideration. Estonian public broadcaster ERR quoted the head of the Internal Security Service as saying that a counterintelligence assessment attributed the attempted attack to Russia and that it was coordinated by Russia’s military intelligence agency, the GRU.
The Estonian-Russian border has three open crossings: Narva, Luhamaa and Koidula, which allow pedestrians and freight to pass. The crossings operate 12 hours a day, from 7 a.m. to 7 p.m. local time, according to ERR’s report on the developments. The proposed closure puts all three crossings under consideration, rather than any one crossing in particular. The potential decision concerns the movement of people and goods through the existing crossing points, according to the broadcaster’s description of their operations. It has not yet been decided whether the restrictions would last for a limited period or indefinitely.
The attempted attack targeted a building belonging to Threod in Viimsi, a company that produces long-range reconnaissance and strike drones, according to ERR. Estonia’s Internal Security Service chief said the building was badly damaged, but that this did not disrupt the company’s ability to produce or deliver its products. He added that no one was injured in the incident. The damage therefore affected the premises, while production and deliveries remained unaffected, according to the security official. The nature of the company’s products directly links the incident to the defense industry, without implying that its production or shipments have stopped.
The Estonian government said eight suspects, all residents of Latvia, were detained in connection with the attempted sabotage. Prosecutors asked the court to place five of them in custody, according to the official statement. This detail distinguishes the detention of the eight suspects from the request for judicial custody, which covered five of them. The statement provided no further details in the information available here about the suspects’ identities or the status of the remaining detainees. The case follows earlier security investigations in which Estonian authorities attributed a fire targeting Milrem Robotics to a tasking by Russian security services.
In the Milrem case, the Associated Press reported that two suspects from Latvia were detained in Latvia on Aug. 17, 2026, and a third suspect was detained the following day. Estonian authorities said Russian security services had tasked the suspects with carrying out the fire targeting the company. More broadly, the agency counted about 200 acts of sabotage and malicious activity across Europe attributed to Russia since the start of the full-scale invasion of Ukraine on Feb. 24, 2022. The figure places the incidents within a period that began with the invasion, while the attempted attack targeting Threod remains the incident that prompted the government to consider closing the crossings. The government is scheduled to discuss in the coming days whether the closure should be temporary or indefinite, with the Foreign Ministry announcing Dec. 1 as the start date.
