Ukraine war: Volodymyr Zelensky visits front-line city of BakhmutUkrainian President Volodymyr Zelensky has made an unannounced visit to the front-line city of Bakhmut, where Ukrainian and Russian forces have fought a fierce, months-long battle.The visit is a significant show of defiance - and a demonstration of support for Ukrainian forces engaged in some of the fiercest battles in recent weeks.His trip will be compared with recent public appearances by the Russian President Vladimir Putin - who on Monday travelled to Minsk for the first time in more than three years to meet Belarusian leader Alexander Lukashenko, a long-time ally.However, this figure cannot be independently verified, and neither Russia nor Ukraine have revealed the full extent of their casualties.Mr Zelensky added: "Since May, the occupiers have been trying to break our Bakhmut, but time goes by and Bakhmut is breaking not only the Russian army, but also the Russian mercenaries who come to replace the wasted army of the occupiers.""
