Russia struck train near Poland border shortly after Boris Johnson and top European officials passed through

Meanwhile, a Russian strike has hit a train near the Ukraine-Poland border shortly after former UK Prime Minister Boris Johnson and other top European authorities had passed through.

Key points

• Poland's Prime Minister Donald Tusk remarked a Russian drone had struck 800m from Polish border.
• In January, President Volodymyr Zelensky condemned as "terrorism" a Russian strike on a crowded passenger train in the north-eastern Kharkiv region that left five individuals dead.
• Earlier this month, six employees of the state railway firm Ukrzaliznytsia were killed after a depot was hit in Kyiv.
• This week, a female conductor died in a Russian drone attack on a passenger train in southern Ukraine.
• Russia has in recent months carried out a number of deadly attacks targeting Ukraine's trains, railway depots and other transport facilities.

No casualties were documented after the Russian strike. It hit the train's engine.

Johnson and some of Europe's most senior security advisers, including the UK's Jonathan Powell, had passed along the same line on their way back from a conference in the capital, Kyiv.

Russia remarked Sunday it struck "railway infrastructure" in western Ukraine, but the former PM stated "I don't know what warped logic drove Putin to blow up a stationary Ukrainian locomotive on the Polish border this morning" and asked "When are we going to give them the air defences they need?"

For context, the Russian attacks have significantly damaged Ukraine's vast train network – the main mode of transportation for millions of Ukrainians as all air travel has been suspended since the start of Russia's full-scale invasion in 2022.
