(Reuters) -Russia's Defence Minister Sergei Shoigu told President Vladimir Putin on Sunday that Moscow and its allies now controlled all of Ukraine's Luhansk region after capturing the last major city, Lysychansk.
There was no immediate response from Ukraine on the Russian claim, which, if confirmed, would mark a significant milestone for Moscow on day 130 of the war.
After being repelled in its initial attempt to capture the capital Kyiv, Russia has focused on driving Ukrainian forces out of the eastern Luhansk and Donetsk regions where Moscow-backed separatists have been fighting Kyiv since Russia's first military intervention in Ukraine in 2014.
The Russian defence ministry said Shoigu had informed Putin of the "liberation" of the Luhansk region thanks to the capture of Lysychansk, once a major coal mining hub.
"As Army General Sergei Shoigu reported [to Putin], following successful military operations, the Russian armed forces, together with units from the people's militia of the Luhansk People's Republic, gained full control over the city of Lysychansk," the ministry said in a statement.
The ministry had said earlier on Sunday that its troops had captured the villages surrounding Lysychansk, encircling the area, and were fighting inside the city.
Calls to the Ukrainian General Staff and Defence Ministry went unanswered. The ministry did not immediately respond to an emailed request for comment.
The Russian defence ministry added that it had struck military infrastructure in the eastern Ukrainian city of Kharkiv, as well as a base used by foreign fighters on the outskirts of Mykolaiv in the country's south.
Russian forces seized Lysychansk's sister city Sievierodonetsk last month, after some of the heaviest fighting seen since Russia sent troops into Ukraine on Feb. 24.
