Estonia thwarts ‘shadow war’ attack, Prime Minister Kaja Kallas tells CNN

Estonia has thwarted a Russian-directed influence operation on its territory, Estonian Prime Minister Kaja Kallas has told CNN.

The operation, extending back to last year, involved a series of attacks, including vandalizing the cars of the interior minister and several monuments.

The Estonian Internal Security Service arrested 10 individuals, including both Russian and Estonian nationals. Estonian officials say more attacks were planned.

“There’s a shadow war going on against our societies,” Prime Minister Kallas told CNN.

“The aim of Russia’s influence operations is to influence our democratic decision making. By making these events public, we raise awareness so that these operations would not have the effect Russia is hoping for.”

Estonian officials told CNN the operation was carried out under the direction of – and in coordination with – Russian security services.

US and allied intelligence agencies have identified the FSB, Russia’s principal security service and the successor to the KGB, as responsible for similar influence operations in several European countries in recent years.

The 10 suspects were detained for “acting on behalf of a Russian special service,” the Estonian government announced Tuesday.

“To the knowledge of the Estonian Internal Security Service, its aim was to spread fear and create tension in Estonian society,” the statement said.

Some of the suspects were recruited on social media, according to Margo Palloson, the director general of the Estonian Internal Security Service.

Russia has not yet responded to the claims.

Earlier, Kallas posted on X, formerly known as Twitter, that “Estonia has successfully stopped a hybrid operation by Russia’s security services on our territory,” adding, “We know the Kremlin is targeting all of our democratic societies.”

Kallas told CNN that her government is making the operation and the Russian links public to dull the effect of the attacks.

Russia carried out a massive hybrid attack on Estonia in 2007, involving both cyber attacks and Russian-organized civil unrest. Estonia, a NATO ally, joined the alliance in 2004.

Intelligence analysts say that a variety of Russian agencies, including the FSB and the SVR (its foreign intelligence service), are involved in hybrid operations throughout eastern Europe.

Estonia has been a particular target because of its substantial Russian-speaking minority – nearly 25% of the population.

The Kremlin is also directly involved in shaping Russian influence operations in neighboring countries, according to Presidential Administration documents leaked last year.

The documents, some of which were seen by CNN, outlined a variety of goals designed to weaken the western orientation of the Baltic States and Moldova.

In March last year, the White House said that “Russian actors, some with current ties to Russian intelligence, are seeking to stage and use protests in Moldova as a basis to foment a manufactured insurrection against the Moldovan government.”

The efforts in the three Baltic states, all members of NATO and the European Union, have generally been lower profile – focused on shifting opinion through social media and pro-Russian activism.
