Estonia Closes Russia Border: All Crossings to Shut From December 1 After Foiled Arson Attack

Estonia closes Russia border crossings from December 1, shutting all three of its land crossings with Russia after Estonian authorities said they had foiled a suspected sabotage attack on a defence company that Tallinn blames on Moscow’s military intelligence service, the GRU.

Foreign Minister Margus Tsahkna announced the closure on Sunday, saying in a post on X that “Russia must understand that hostile actions against Estonia come with consequences.” Prime Minister Kristen Michal confirmed the move in a statement the same day, saying the crossings would close from December 1 and giving no date for when they might reopen.

Estonia closes Russia border after foiled sabotage

Estonian authorities detained eight people overnight on suspicion of an attempted arson attack on drone maker Threod Systems, which they said had been ordered by Russia’s GRU military intelligence service. No one was injured in the attempted attack, according to the authorities.

Tsahkna said the attempted sabotage was “yet another reminder that Russia’s hostile activities extend far beyond Ukraine” and that “hostile actions must have consequences.” He said he expected further sanctions targeting Russian individuals and entities to be adopted at a meeting of foreign affairs ministers in Brussels on Monday.

What closes on December 1

Estonia currently has three open border crossings with Russia, at Narva, Luhamaa and Koidula, which admit pedestrians and freight, according to Estonian public broadcaster ERR. All three will close from December 1.

“If Russia continues its hybrid operations in Estonia, and we know that Russian intelligence services exploit border crossings to exert influence over people, we must be prepared to reduce the risks we face,” Prime Minister Michal said in a statement on Sunday.

“Closing the border would reduce the threat to people in Estonia and send a clear message that attacks on Estonia’s defense industry and defense capabilities are unacceptable,” he added.

Reactions and wider context

Ukraine commended Estonia for the move. Foreign Minister Andrii Sybiha said in a post on X that “Estonia has shown that Russian sabotage can and should have consequences beyond diplomatic condemnation,” adding that “this approach deserves wider support across Europe.”

There was no immediate comment from Moscow on Estonia’s accusations or its decision to shut the border crossings. Moscow has regularly denied accusations by European authorities of involvement in sabotage operations, and Russia has long been accused of carrying out sabotage and other hybrid attacks against Europe.

Estonia is a NATO and European Union member state and a strong supporter of Ukraine. In September, European officials pointed the finger at the Kremlin after a series of incidents that appeared to target NATO members, including a drone strike on a railway line near Ukraine’s border with Poland and a drone shot down in Lithuania.
