Russian meddling probably didn’t affect the referendum result – but the Kremlin’s motives for wanting to undermine the EU still matter

Russian territorial aggression against Ukraine didn’t feature much in the Brexit referendum campaign. It made headlines briefly when Boris Johnson blamed Moscow’s 2014 annexation of Crimea on the European Union.

According to the Vote Leave frontman, Vladimir Putin’s land grab was a consequence of Brussels making foreign policy “on the hoof” and having “pretensions to running a defence policy”.

German services detained two Turkish citizens on 12 October over the 23 September arson attack on a Starlink ground station in Wola Krobowska, near Warsaw, Poland’s Internal Security Agency (ABW) said. Both are suspected of arson, and Polish officials blame Russian intelligence. RMF24 later reported that German police also detained two more people who may be connected to the attack.

Poland is one of the main corridors for Western aid to Ukraine, and Polish Foreign Minister Radosław Sikorski has said Poland spends about $50 million a year on Ukraine's Starlink service. That puts Polish infrastructure in the path of a Russian campaign that already hacks cameras to track arms heading east.

Fingerprints, DNA, and a route out

The men were held under European arrest warrants and now await transfer to Poland. Interior Minister Marcin Kierwiński wrote that the suspects would face charges of “subversion, sabotage on behalf of a foreign intelligence service” after their transfer to Poland. Polish authorities issued European arrest warrants for the suspects, who were subsequently detained in Germany.

Police chief Marek Boroń said investigators reconstructed how the suspects prepared the attack and fled. “We have secured recordings pointing to this specific action. We have fingerprints, the perpetrators’ DNA, how they moved, when they came to Poland, and when they were evacuated from our country,” he said. One suspect lives in Germany, and the other had been ordered to leave the country, he added.

Warsaw points at Moscow

Prime Minister Donald Tusk called the fire another act of Russia's hybrid war and promised the saboteurs will answer to Polish justice.

“We have no doubt that Russian intelligence services are behind this act of sabotage,” said Tomasz Siemoniak, the minister coordinating Poland’s special services.

Those services increasingly turn to people tied to the criminal world, he added.

Two more possible links

German counterterrorism officers detained a woman in Berlin, and a man is also in German custody, Polish radio RMF FM reported, citing its reporter. Both may be linked to the arson. The woman allegedly picked up the Turkish men near Łódź after they entered Poland from Germany, then drove them to Wola Krobowska. The man’s role is still being examined.
