WARSAW

Poland on Wednesday announced the closure of the last operating Russian consulate in Poland, in the northern city of Gdansk, and signaled further retaliatory steps would be taken after attacks on Polish rail infrastructure over the weekend, said the nation’s foreign minister.

“Russia has not stopped these attacks; it is escalating them,” Radoslaw Sikorski told a press conference in Warsaw about the incidents, which Russia has denied any responsibility for. “When the intention of sabotage is human casualties, we are dealing with state terror. For that reason I have decided to close the Russian Consulate in Gdansk. This will not be our full response.”

He added that he would formally request the extradition of the suspected saboteurs from Belarus “today or tomorrow.”

Sikorski also revealed new findings from Poland’s intelligence services regarding two recent attempts to derail passenger trains on key rail corridors linking Warsaw to Lublin and Deblin, to the southeast

According to Sikorski, investigators have determined that the perpetrators were Ukrainian citizens cooperating with Russian intelligence, specifically the GRU, which he said routinely hires proxies under false identities.

“This will be met with our response, not just diplomatic, which we will inform you about in the coming days,” he said.

Prime Minister Donald Tusk confirmed earlier in the week that Polish services had identified two Ukrainian nationals responsible for the sabotage who had already fled Poland into Belarus.

One of the attacks involved the detonation of an explosive device on the Warsaw–Lublin line near Mika station. In the second, saboteurs reportedly damaged the traction system and placed a metal clamp on the tracks to force a derailment.

Sikorski also tied the sabotage to political rhetoric around Poland’s Nov. 11 Independence Day, sharply criticizing a nationalist march in Warsaw during which an EU flag was burned. He rebuked Karol Nawrocki, the nation’s president, for ignoring Russia’s aggression in his speech while accusing Polish political opponents of surrendering sovereignty to the EU.

The latest attacks follow a string of suspected Russian-linked operations across Poland and the region over the past year.

Moscow has consistently denied any connection to the incidents.
