Ukraine war live updates: Russia slams $61 billion U.S. aid package, saying it will 'ruin' Ukraine and create more carnage

This is CNBC's live blog tracking developments on the war in Ukraine. See below for the latest updates. 

Ukraine has received a reprieve after the U.S. House of Representatives passed a $61 billion foreign aid package for Kyiv over the weekend. Russia slammed the new funding, saying it fuels global crises.

House lawmakers approved the aid Saturday despite long-standing objections from hardline Republicans; the bill now passes to the Democratic-majority Senate, which is expected to approve the legislation later this week before it's passed to President Joe Biden to sign it into law.

The aid is a lifeline for Ukraine, whose forces in the east of the country have had to ration their usage of shells amid shortages of supplies; Russian forces have been making gains in the Donbas region, with Ukraine pleading for more air defense systems, artillery and ammunition to turn the tide in the war.

Ukrainian President Volodymyr Zelenskyy thanked U.S. lawmakers saying the bill passed by the House "will keep the war from expanding, save thousands and thousands of lives, and help both of our nations to become stronger." He urged the Senate to pass the bill as quickly as possible.

Russia has reacted angrily to the U.S. $61 billion aid package for Ukraine, claiming that it will only lead to more carnage in the conflict.

Russian Foreign Minister Sergei Lavrov warned Monday that Russia and the West are on the brink of a potential nuclear confrontation.

"Westerners are dangerously balancing on the brink of a direct military clash between nuclear powers, which is fraught with catastrophic consequences," the minister said in a video message to the participants of the Moscow Nonproliferation Conference, news agency RIA Novosti reported.
