Russia’s Defence Ministry said in a brief statement its forces had “liberated” the town. Reuters could not independently confirm its fall.
DeepState, a Ukrainian open-source mapping site that charts the front lines, showed Ukraine’s forces controlling the western part of the town.
Russia has been slowly grinding forward in eastern Ukraine as talks to end the three and half year war have failed to make progress towards a ceasefire, prompting U.S. President Donald Trump to threaten new sanctions on Russia and buyers of its exports from next week.
Moscow’s forces are also mounting intense pressure on the city of Pokrovsk, 60 km (37 miles) southwest of Chasiv Yar.
Military analyst Emil Kastehelmi, co-founder of the Finland-based Black Bird Group, said it was likely that battles were continuing near Chasiv Yar.

“The terrain of Chasiv Yar has favoured the defender. Forested areas, waterways, hills and a varied building stock have enabled Ukraine to conduct a defensive operation lasting over a year, in which the Russians have made minimal monthly progress,” he told Reuters.
Kastehelmi said it was likely that the town’s fall, if confirmed, would create conditions for Russia to advance further in eastern Ukraine, but still only gradually.
“The fall of the city to the enemy is nevertheless a challenging situation for Ukraine, as it will bring the Russians closer to Kostiantynivka, which Russia is now approaching from several directions,” he said.
“The logistics in the area will also be affected, as Russians can bring drone teams even closer.”
The battle for Chasiv Yar began in April last year, when Russian paratroopers reached its eastern edge. Russian state media reported then that Russian soldiers had begun phoning their Ukrainian counterparts inside the town to demand they surrender or be wiped out by aerial guided bombs.
The town, now in ruins, had a pre-war population of more than 12,000 and its economy was based around a factory that produced reinforced concrete products and clay used in bricks.
It lies just west of Bakhmut, which Russia captured in 2023 after one of the bloodiest battles of the war.
