Gavin Grey: UK correspondent on Russian drone striking train behind Boris Johnson and other dignitaries near Ukraine border

A Russian drone has hit a train near the Ukraine-Poland border, moments after former UK Prime Minister Boris Johnson and other top European security officials had been present. No one died in the attack, and all passengers were safely evacuated. Johnson had been passing along the same line on a different train, returning from a conference in Kyiv. UK correspondent Gavin Grey says there's plenty of speculation behind the motives of the strike, with Ukraine claiming Johnson's train was the intended target.
