Ukrainian 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, writes BBC.

He met troops and handed out awards to soldiers, the presidency said.

For months, Bakhmut has been a key target for Russian forces in the Donetsk region, and has been extremely badly damaged. However, Ukrainian forces have been able to hold back the advance.

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.
