A Ukrainian soldier fires toward Russian positions in Bakhmut on February 16. Moscow's forces claim to be gaining ground as nearly round-the-clock shelling rains down on the shattered city, which Ukrainian President Volodymyr Zelenskiy has called "our fortress."
Located astride two major crossroads, Bakhmut, which had a prewar population of 70,000, has been almost completely destroyed during intense fighting.
Despite the fighting and cold winter weather, an estimated 6,000 civilians remain in the city. Ukrainian authorities are urging them to evacuate while they still can.
Among the Ukrainian forces defending Bakhmut are members of the country's State Border Guard Service. This guard waits at the entrance of a shelter for an order to move to a mortar position.
