2 years of Ukraine-Russia war: Troops face mounting challenges on the front line

Ukraine marked two years since Russia’s full-scale invasion on Saturday, with a string of foreign dignitaries and officials expected to visit the capital, Kyiv, in solidarity as Ukrainian forces run low on ammunition and weaponry and Western aid hangs in the balance.

A somber mood hangs over the country as the war against Russia enters its third year, and Kyiv's troops face mounting challenges on the front line amid dwindling ammunition supplies and personnel challenges, and having withdrawn from a strategic eastern city that handed Moscow one of its biggest victories.

The anniversary comes after President Volodymyr Zelensky sacked top military commander Valerii Zaluzhnyi, replacing him with Col. Gen. Oleksandr Syrskyi, marking the most significant shakeup of top brass since the full-scale invasion.

Russia still controls roughly a quarter of the country after Ukraine failed to meet expectations with its summer-time counteroffensive not producing major breakthroughs. Meanwhile, millions of Ukrainians continue to live under precarious circumstances in the crossfire of battles, and many others face constant struggles under Russian occupation. Most are still waiting for a Ukrainian liberation that hasn't come.

Foreign officials are expected to descend on the capital to meet with Zelensky and other Ukrainian officials and express their continued support for the country as it fights Moscow's troops and prepares for European Union membership.
