Russian forces have entered the outskirts of Sievierodonetsk, a major city in Ukraine’s Donbas region, that has been a military objective of Russia in recent weeks, an official said.

Governor Serhiy Gaidai of Luhansk, which is just over 50 miles away, said Russian forces advanced into the city’s eastern side after an assault earlier in the day left two civilians dead and wounded five others, Reuters reported.

Russian Foreign Minister Sergei Lavrov said Sunday the "liberation" of the Donbas region was an "unconditional priority" in the war, per the report.

Like in Mariupol before it, Ukrainian forces in Sievierodonetsk continue to resist Russia’s military dominance and have slowed Russia’s advance with their unwillingness to surrender even an inch of the city, according to the report.

In an address to the country Sunday evening, Ukrainian President Volodymyr Zelenskyy said Russian forces indiscriminately bombed the town as "some 90% of buildings are damaged."

"As a result of the Russian strikes at Severodonetsk, the entire critical infrastructure of the city has already been destroyed," Zelenskyy added. "More than two-thirds of the city's housing stock has been completely destroyed."

Zelesnkyy recognized capturing the town was a "fundamental task" for Russia’s military and "don't care how many lives they will have to pay for this attempt to raise the Russian flag" in its capital."

The Ukrainian president was not without hope and said his military was actively fighting to defend against Russia’s invasion.

"We are doing everything to repel this offensive," he said. "There was not a day that we did not try to find more weapons, more modern weapons to defend our land, to defend our people."
