Several top EU politicians have called a Russian drone strike on a passenger train ​on Ukraine's border with Poland a bid by Moscow to intimidate Kyiv's allies that should be met with even more resolution.

In the incident, a drone hit the train's locomotive at a railway station in the Volyn region, some 2 kilometers (1.24 miles) from the border, shortly after a diplomatic ‌train carrying former British ​Prime ⁠Minister Boris Johnson and other ⁠European ​diplomats had been at the station.Russia carried out two drone strikes at the Ukraine-Poland border on SundayImage: Sylwester Uchanski/REUTERS

What did EU leaders say about the train attack?

"It [the attack] is clearly meant to scare Western countries from supporting Ukraine, from going to Ukraine to show support," the EU's foreign policy chief, Kaja Kallas, said.

"I ​think we should act the opposite. ​We should show that we are ⁠there ​for Ukraine ​and we are ​not scared," ‌she told reporters in ​Finland, ⁠where she attended ⁠a ​summit on Arctic strategy.
