The Russian military operation in Ukraine "will never be a victory" for President Vladimir Putin, US President Joe Biden said Tuesday in light of heavy western sanctions on Moscow, which failed to hinder the Russian advances in Ukraine.

Biden, whose country's insistence on Kiev joining NATO and ignorance of Russian proposals on security guarantees put Ukraine in this situation altogether, underlined that the crisis was exacting a "horrible price" and had already resulted in two million refugees.

"Russia may continue to grind out its advance at a horrible price but this much is already clear - Ukraine will never be a victory for Putin," claimed the President whose administration lost a 20-year war on Afghanistan just a few months ago.

Biden, in a bid to paralyze the Russian economy, went on and banned imports of Russian oil to the United States.

"Putin may be able to take a city, but he'll never be able to hold the country," he claimed, despite Moscow stressing that it did not intend to occupy Ukraine.

The situation in many Ukrainian cities, particularly large cities, has devolved into a humanitarian disaster as a result of Kiev's inability to ensure the operation of humanitarian corridors, according to a statement issued by Russia's interdepartmental coordination headquarters for humanitarian response in Ukraine.

Addressing the humanitarian crisis, much of which has been created by Kiev, Washington, and Brussels, Biden pledged the United States would stand by its allies.

"The United States will share in the responsibility of caring for the refugees so that the costs do not fall entirely on the European countries bordering Ukraine," the democrat alleged.

"Putin's war," Biden boldly claimed, "Has caused an enormous suffering and needless loss of life - of women, children, everyone. He also accused his Russian counterpart of targeting civilians indiscriminately - in schools, hospitals, and apartment buildings. 

Russian defense ministry spokesperson Igor Konashenkov cited confirmed data as saying multiple rocket launchers had been placed among the houses in the private sector on Zhylyardi Street in Kievskyi District, Donetsk.

"But Putin seems determined to continue on his murderous path no matter the cost," he asserted, despite the provocations and crimes of the Kiev-backed Azov Battalion.

"When the history of this war is written, Putin's war on Ukraine will have left Russia weaker and the rest of the world stronger," he vowed, despite the Western economy practically crashing without the Russian contributions to it.
