EU foreign policy chief Kaja Kallas said Monday that Russian strikes hitting a Warsaw-bound train near Ukraine’s border with Poland were designed to discourage Western support for Ukraine. Her comments were reported by France 24 from Brussels.

Kallas said the incident occurred shortly after senior Western figures had passed through the area. She characterized the timing and location of the strikes as an attempt to influence countries and officials demonstrating support for Kyiv.

“It is clearly meant to scare Western countries from supporting Ukraine, from going to Ukraine to show support,” Kallas said, according to France 24. The EU’s top diplomat did not, in the supplied material, provide further details about the strike, the train, or any reported casualties or damage.

Kallas called on countries backing Ukraine to react in the opposite way to what she described as the intended threat. “We should do the opposite,” she said, urging continued support for Kyiv and visits to Ukraine as a sign of solidarity.

The report did not include a response from Russia or additional information about how European governments might act. It also did not specify what measures, if any, the European Union was considering following the incident. France 24 said its correspondent Dave Keating was reporting from Brussels.
