Russian strike on train "terror knocking on EU's door'

The Kremlin said on Monday it would keep striking targets across the "whole" of Ukraine, when asked about a rare drone attack on the Polish border that has rattled Warsaw and its European allies.

NATO-member Poland said on Sunday that Russia had hit a railway locomotive inside Ukraine, about two kilometres (one mile) from their shared border, just days after Kyiv said it had hit a crossing at its border with Moldova.
