Ukrainian President Volodymyr Zelensky evoked comparisons to former British Prime Minister Winston Churchill's grit in defiant remarks before Parliament on Tuesday.

Zelensky compared Ukraine's struggle as Russia invades his country to the United Kingdom's fight against Germany in World War II in remarks similar to Churchill's vow to "fight [Nazis] on the beaches." The Ukrainian leader told the House of Commons that the Ukrainians were vying to save their country in "just the same way as you once didn't want to lose your country when Nazis started to fight your country and you had to fight for Britain."

"We will not give up and we will not lose," Zelensky said. "We will fight to the end, at sea [and] in the air. We will continue fighting for our land, whatever the cost."

The Ukrainian president also mourned the 50 children who were killed in a "war that [Ukrainians] didn't start and [they] didn't want," some of whose deaths led to images circulating in news publications.

"These are the children that could have lived, but these people have taken them away from us," Zelensky said, according to the Daily Mail.

More than 80% of Ukrainians are confident in their ability to repel Russia's invasion, according to a Gradus Research Company report published Friday. The poll, which was conducted between Feb. 28 and March 1 and featured 2,144 respondents, also showed citizens believe "the power of Armed Forces of Ukraine," the "cohesion and resistance of Ukrainian society," and "West military support" will be the "guarantees of Ukraine's victory."

While stopping short of deploying troops, Western powers are indicating their support for Ukraine through diplomatic and economic channels. President Joe Biden announced a ban on oil and natural gas from Russia on Tuesday, yielding to congressional pressure to hit one of Moscow’s crucial economic lifelines as it continues its attacks on Ukraine. Biden warned the new measures would impose costs on U.S. citizens, but he blamed Putin's invasion for the rising gas prices.

The London Bullion Market Association suspended its accreditation of six Russian precious metals refiners on Monday, effectively barring them from selling gold and silver on the world's largest market. Shortly after the announcement, a bipartisan group of U.S. senators introduced a bill aimed at preventing Russia from liquidating gold to circumvent sanctions.
