Ukraine stands firm in defense of Bakhmut against Russian attack.

Ukrainian troops are defending positions in Bakhmut against a relentless push by Russian forces to capture the city. Both sides claim successes in the longest-running battle since Russia launched its full-scale invasion of Ukraine more than a year ago. Russian troops have enveloped the city from three sides, leaving only a narrow corridor leading west. Ukrainian officials said that Ukrainian Ground Forces shot down a Russian fighter jet near Bakhmut and made gains in northern parts of the city.
