As the war nears its two-year mark, Russia has claimed complete control over a key city in eastern Ukraine. Russian troops took over the industrial hub of Avdiivka after months of fighting. Russian President Putin congratulated the military for the "important victory". Ukraine said it had withdrawn its soldiers from Avdiivka. Kyiv's forces struggle due to ammunition shortage. Meanwhile, Ukrainian President Volodymyr Zelensky warned allies of an "artificial deficit" of arms for his country.
