Chasiv Yar, eastern Ukraine — Ukraine's ammunition starved troops pulled back from two more villages in the country's war-torn east this week, ceding them to Russian forces who've capitalized on their enemies' shortages to seize more territory after taking the hard-fought city of Avdiivka about two weeks ago. After punishing battles that decimated Bakhmut and then Avdiivka — cities that stood as symbols of Ukrainian resistance for months, even years, but ultimately fell to Russian firepower — Russia's forces have turned their sites and their guns on the nearby city of Chasiv Yar.
