Russian Defence Minister Sergei Shoigu said on Friday Moscow was nearing full control of Ukraine’s eastern separatist region of Lugansk.
Russian President Vladimir Putin sent troops to Ukraine on February 24 under the guise of protecting the Russian-speaking population there, especially in the breakaway regions of Lugansk and Donetsk.
Russia recognized the independence of the separatist republics shortly before launching the military action.
“The liberation of the Lugansk People’s Republic is nearing completion,” Shoigu said at a televised ministry meeting.
Separately, Shoigu said 1,908 Ukrainian soldiers had surrendered at the besieged Azovstal steelworks in the port city of Mariupol.
Russia claimed control of the strategic city in southeastern Ukraine in late April, keeping the remaining Ukrainian forces blocked inside the giant steel plant.
Shoigu said Ukrainian authorities in early May attempted to retake the strategic Snake Island in the Black Sea that was seized by Russian troops early in the conflict.
“This questionable action turned out to be a complete failure,” Shoigu said.
Snake Island became a symbol of Ukrainian resistance after a radio exchange went viral at the start of the conflict, in which Ukrainian soldiers used an expletive in rebuffing a demand by the Russian warship Moskva to surrender.
The Moskva sank in the Black Sea in mid-April following what Moscow said was an explosion on board. Ukraine and the US said the warship was hit with missiles.
