Ukraine remains in control of a key supply route into Bakhmut, a military spokesperson said on Saturday.
Russian forces have been trying for 10 months to punch their way into the shattered remains of what was once a city of 70,000. Kyiv has pledged to defend Bakhmut, which Russia sees as a stepping stone to attacking other cities.
"For several weeks, the Russians have been talking about seizing the 'road of life,' as well as about constant fire control over it," Serhiy Cherevatyi, a spokesperson for Ukrainian troops in the east, said in an interview with local news website Dzerkalo Tyzhnia.
"Yes, it is really difficult there ... (but) the defense forces have not allowed the Russians to 'cut off' our logistics."
The "road of life" is a vital road between the ruined Bakhmut and the nearby town Chasiv Yar to the west - a distance of just over 17 km (10.56 miles).
Ukraine's top military command said in its daily update on Sunday that its forces had repelled 58 Russian attacks over the past day along the part of frontline stretching from Bakhmut through Avdiivka and on to Maryinka further south in the Donetsk region.
