The defense ministry stated that Russia hit over 90 military sites in Ukraine, killing at least 500 Ukrainian soldiers and destroying dozens of armored vehicles, artillery, and other military hardware.
Additionally, Russia stated that it attacked two ammunition dumps in eastern Ukraine's Kharkiv region.
Russia's foreign minister warned the world not to underestimate the grave risks of nuclear conflict. NATO's provision of arms to Ukraine "in essence" entailed the Western alliance engaging in a proxy war with Russia.
Additionally, Russia's top diplomat warned Ukraine that his country had launched operations targeting rail and petroleum infrastructure located far from the front lines of Moscow's new eastern incursion.
Russian state media interviewed foreign Minister Sergei Lavrov about the necessity of preventing World War Three and whether the current situation was akin to the 1962 Cuban Missile Crisis.
"The risks now are considerable," Lavrov stated in an interview transcript posted on the ministry's website.
"I would not want to artificially inflate such risks. That would be ideal for many. The risk is grave and present. And it is not to be underestimated."
The US has been shipping additional armament to Ukraine, claiming that Western partners' assistance makes a difference in the two-month-old conflict.
"Russia is in decline. Ukraine is prospering," US Secretary of State Antony Blinken claimed Monday, following a daring visit to Kyiv by he and the US Secretary of Defense to meet with President Volodymyr Zelensky.
Blinken stated that Washington had approved a $165 million sale of ammunition — non-US ammunition, primarily but not exclusively for Ukraine's Soviet-era weapons — and will also give over $300 million in finance to purchase more supplies.
Dmytro Kuleba, Ukraine's foreign minister, said he saw Russia's scaremongering as a show of weakness.
After Lavrov's interview, Kuleba stated on Twitter that Russia has lost its "last hope to scare the world off supporting Ukraine," "This only means Moscow senses defeat."
Meanwhile, the British Defense Ministry announced Tuesday that Russian forces had gained control of the Ukrainian city of Kreminna in the Lukansk region following days of street-to-street battle.
"The city of Kreminna has reportedly fallen, and heavy fighting has been reported south of Izium as Russian forces attempt to advance from the north and east towards the cities of Sloviansk and Kramatorsk," the British military said in a tweet. It did not specify how it learned the city had fallen, located 575 kilometers (355 miles) southeast of Ukraine's capital, Kyiv. The Ukrainian administration did not immediately respond to a request for comment.
On Monday, Russia shifted its firepower away from the front lines, with missiles and warplanes targeting targets further behind the front lines to sabotage Ukrainian supply attempts.
Five railroad stations in central and western Ukraine were struck, killing one employee, according to Oleksandr Kamyshin, Ukraine's state railway's head. The bombardment included a missile attack on Lviv, a city in western Ukraine near the Polish border that has grown in size due to Ukrainians fleeing turmoil elsewhere.
Ukrainian authorities reported that Russian strikes killed at least five persons in the central Vynnytsia area.
