“Our troops have gone into a local offensive around Orikhiv,” the head of Moscow’s installed authorities in Ukraine’s Zaporizhzhia region, Vladimir Rogov said, according to Russian state media.
Rogov alleged the front had slightly shifted and that some Ukrainian troops had retreated.
“Our troops are holding their positions,” he said.
“The territory of the Zaporizhzhia region liberated from Ukrainian fighters is gradually increasing.”
The Kremlin has claimed it annexed the Zaporizhzhia region — and three other Ukrainian regions — despite not controlling them entirely.
While Moscow occupies large swathes of the south of the Zaporizhzhia region, its main city, also called Zaporizhzhia, has not fallen to Russian forces.
Russia has vowed to take control of the rest of southern and eastern Ukraine that it has claimed as its own.
The front in southern Ukraine has been largely frozen since Moscow withdrew from the major city of Kherson in November.
The Ukrainian army did not mention Orikhiv in its daily report on Thursday.
The fiercest fighting in Ukraine in recent weeks has centred further north, in eastern Ukraine, with Moscow claiming to have captured the town of Soledar, outside Bakhmut.
Intense battles over Bakhmut, which Russia has been trying to seize for months, is continuing.
