Estonia will close all border crossing points with Russia from December 1, Foreign Minister Margus Tsahkna has announced.

Axar.az reports that, in a post on X, Tsahkna said the decision followed evidence that Russia's military intelligence service, the GRU, had ordered a sabotage attack against an Estonian defence industry company.

"Estonia will close all Estonian-Russian border crossing points as of 1 December. Russia must understand that hostile actions against Estonia come with consequences. Attempts to intimidate, destabilise, or undermine our security will not go unanswered," Tsahkna wrote.

"Closing the border crossings will reduce Russia’s ability to conduct hostile activities in Estonia and strengthen our efforts to prevent sanctions circumvention," he added.

Tsahkna added that he had informed his Finnish, Latvian, and Lithuanian counterparts of the decision.
