NATO Secretary General Jens Stoltenberg warned Wednesday the eastern Ukrainian city of Bakhmut might fall to Russia in the coming days following months of intense fighting. His remarks came as Russia's Wagner mercenary group, which has spearheaded the attack on Bakhmut, claimed to have captured the eastern bank of the industrial town, devastated in the longest battle since Moscow invaded Ukraine a year ago. Wagner chief and Kremlin ally Yevgeny Prigozhin said on social media Wednesday that his forces "have taken all of the eastern part of Bakhmut", a salt-mining town with a pre-war population of 80,000.
