Russian strike hits Kyiv-Warsaw rail line 2 km from Polish border, near NATO territory

A Russian attack struck a passenger train on the Kyiv-Warsaw line on Sunday, just two kilometers from the Polish border, marking the closest strike to NATO territory since the war began. The incident raises the risk of direct NATO-Russia escalation, though it remains unclear whether the strike was deliberate or collateral. This development signals a potential expansion of the conflict's geographic scope and heightens alliance security concerns.
