Russia hits Ukrainian train shortly after Boris Johnson and top European officials leave station

BBC News reports that Russia struck a Ukrainian train at a station on the Polish border shortly after former UK Prime Minister Boris Johnson and a group of top European officials had left. Johnson described the target as a stationary Ukrainian locomotive, telling the BBC: "I don't know what warped logic drove Putin to blow up a stationary Ukrainian locomotive on the Polish border this morning."

The timing of the strike, so soon after a former British prime minister and senior European officials departed the station, is what makes it notable. It also puts the war's reach in sharp relief: a Ukrainian train hit at a station on the Polish border sits close to NATO's eastern flank, where any escalation carries outsized risk.

What to watch now is whether more details emerge about the attack and any casualties, and how European governments respond to a strike that landed so close to the border with NATO territory.
