Estonia Will Seal Its Russian Border on December 1 After Foiling a GRU-Linked Plot Against a Drone Maker

Estonia says it will close every one of its border crossings with Russia starting December 1, after its security services stopped what officials describe as a sabotage attack ordered by Russian military intelligence against an Estonian drone manufacturer, AFP reported Sunday. The Jerusalem Post also reported the planned closure.

Foreign Minister Margus Tsahkna announced the decision on social media, saying the government has "irrefutable evidence" that Russia's GRU ordered the attack on a company in Estonia's defense industry, according to AFP. He did not say publicly what that evidence is.

The target was Threod Systems, which builds reconnaissance and attack drones, according to AFP. Estonia's security service said the attackers planned to set off an explosive device and set the building on fire, AFP reported. The attempted attack took place in Viimsi, just north of the capital, Tallinn, the Helsinki Times reported.

Chief prosecutor Astrid Asi told journalists that eight people who live in neighboring Latvia have been detained, AFP reported.

The decision covers Estonia's three crossings with Russia, at Narva, Luhamaa and Koidula, which now handle pedestrians and freight, according to AFP. Prime Minister Kristen Michal asked Interior Minister Igor Taro to prepare the closure, and Taro proposed shutting all road crossings to both people on foot and vehicles from the start of December, the Helsinki Times reported.

Taro said Estonian residents and truck drivers now in Russia will have roughly two weeks to come home before the restrictions take effect. The government is set to decide at the end of the coming week whether the closure will be temporary or open-ended, the Helsinki Times reported. The move will affect travelers and freight, including people who travel between Finland and Russia by way of Estonia.

Michal said the closures are meant to reduce security threats and keep Russian intelligence services from using the crossings, according to AFP. Tsahkna also tied the step to limiting Moscow's ability to run hostile operations inside Estonia and to stopping sanctions evasion.

It is not the first time Tallinn has pointed at Moscow. In September, Estonia formally blamed Russian special services for an August arson fire at a Tallinn building used by Milrem Robotics, a maker of unmanned ground vehicles that supplies Ukraine, the Associated Press reported. The Kremlin dismissed that accusation as unfounded at the time. Sunday's reports noted that Tallinn tied the Milrem fire to the same agency it now blames for the drone-factory plot.

Moscow had not commented on the latest allegations as of Sunday, AFP reported. Russia has repeatedly denied running sabotage operations in Europe.

The case puts a spotlight on the sabotage threat facing defense companies on NATO's eastern flank, and on a small ally that is willing to accept a real economic cost to protect its people and its industry. Estonia has not released the evidence behind its accusation, and the eight suspects have not yet been tried. The government's decision later this week on how long the border stays shut, and any answer from the Kremlin, are the next things to watch.
