Boris Johnson was among those who narrowly avoided a Russian drone strike after a train carrying the former British prime minister and a group of senior European security figures passed through the Ukraine-Poland border shortly before another train was hit.The Russian drone struck the locomotive of a passenger train near Yahodyn in western Ukraine, just 2km from the Polish border, in an attack Ukrainian authorities warned showed Putin’s war was edging dangerously close to NATO territory.No one was injured, with passengers on the targeted train evacuated shortly before the strike.But Ukrainian Railways said it was “quite possible” the Russian drone had been targeting the diplomatic train carrying Johnson and other European officials, including former CIA director David Petraeus.The train carrying the high-profile group had passed through the area shortly beforehand while returning from a major security conference in Kyiv.Ukrainian Railways said the train had departed earlier than planned after authorities altered schedules in real time because of the continuing threat of Russian attacks.The railway authority said passengers on the train that was eventually hit had been ordered to evacuate just 15 minutes before the Russian jet-powered drone struck its locomotive.Johnson later condemned the attack, saying he could not understand the “warped logic” behind Russia blowing up a stationary Ukrainian locomotive.“What we can say for sure is that this is the kind of random and senseless attack Ukrainians are enduring every day – even on civilian railways,” he wrote on X.He urged Western nations to provide Ukraine with the air defences it needs to protect its cities and infrastructure from Russia’s increasingly sophisticated attacks.The strike came as Russia unleashed a massive overnight barrage across Ukraine involving more than 450 drones and missiles.At least six people were killed and more than 40 injured, with western Ukraine – which is traditionally less exposed to the heaviest fighting – among the areas hit hardest.Ukrainian officials said the attack on the railway locomotive occurred near the Dorohusk-Yahodyn crossing, one of the key routes connecting Ukraine with Poland.A truck was also hit less than 1km from the border, according to Ukrainian and Polish authorities, while the border crossing was briefly disrupted before operations resumed.The attacks prompted air-raid warnings in Poland and fuelled fresh fears that Russia’s war could spill directly into NATO territory.Ukrainian Foreign Minister Andrii Sybiha described the strikes as “Putin’s terror ‘knocking’ directly on the doors of the EU and NATO”.“Russian barbarians are at your gate, dear partners,” he wrote.Polish Prime Minister Donald Tusk held an emergency meeting after the attacks and warned that the intensifying Russian campaign was moving closer to his country’s border.“The escalation of the actions from the Russian side is becoming a reality, and they are getting closer and closer to our border,” Mr Tusk said.He said Poland’s intelligence services and allied agencies had warned that an attack targeting Ukrainian border crossings was likely.“We knew that the Russian plan would include an attempt to disrupt, paralyse, and perhaps even destroy Ukrainian border crossings,” he said.Russia defended the attacks, saying it had targeted railway infrastructure in western Ukraine being used to transport military cargo from European countries.The Russian Defence Ministry said strikes had continued against infrastructure used to move military supplies from Europe.Ukraine, meanwhile, relies heavily on its railway network to transport people, supplies and military equipment, with its airspace closed to civilian aviation since Russia’s full-scale invasion began in 2022.The railway system has increasingly come under attack.Earlier this week, two people were killed after Russian drones struck a border crossing between Ukraine and Moldova, while a female conductor was killed in a separate attack on a passenger train in southern Ukraine.Six Ukrainian railway employees were also killed when a depot in Kyiv was struck earlier this month.The latest attack came amid a broader escalation in long-range strikes by both Russia and Ukraine against infrastructure far from the front lines.In Lithuania, authorities briefly closed Vilnius airport after a possible drone sighting triggered a NATO response, including the scrambling of at least one fighter jet.The suspected drone, however, turned out to be a flock of birds.
