Former British Prime Minister Boris Johnson was traveling through Ukraine in a train when a Russian drone struck the railway line behind his train, according to a report by The Telegraph.

Johnson was making his way toward the Polish border when the attack hit the rail route. 

The former prime minister has remained one of Ukraine’s most outspoken supporters since Russia launched its full-scale invasion. 

His latest visit comes as he continues to argue that Western countries need to maintain pressure on Moscow and provide Ukraine with the military support needed to defend itself.
