This was CNBC's live blog tracking developments on the war in Ukraine.

Finance ministers of G7 countries are meeting in Italy this week with Ukraine high on the agenda. Some have floated the possibility of G7 states helping Kyiv with as much as $50 billion in loans funded by frozen Russian assets, a controversial idea that has not yet received full approval from the Western community.

France tested a nuclear-capable missile on Thursday, a day after Russia announced nuclear drills, with the move by Moscow seen as a response to French President Emmanuel Macron's previous assertion that he would not rule out sending French troops into Ukraine.

Hungarian Prime Minister Viktor Orban, known to be a friend to President Vladimir Putin and a vocal critic of Ukrainian President Volodymyr Zelenskyy, cast doubt on some Western leaders' warnings that Putin would invade more of Europe if he succeeded in Ukraine.

"I do not consider it logical that Russia, which cannot even defeat Ukraine, would all of a sudden come and swallow the Western world as a whole," he said in a radio interview, according to Reuters.

World Bank chief reportedly open to managing G7 loan to Ukraine

World Bank President Ajay Banga said he is "absolutely" open to the prospect of managing a G7 loan for Ukraine derived from earnings on frozen Russian assets, Reuters reported Friday.

In an interview with Reuters at the G7 finance meeting in Stresa, Italy, Banga said he has not been approached for the role, nor is he party to the loan discussions, however he said he would be prepared to do it.

"All I know is that if they do decide to give it to us, would I be ready? Yeah," Banga said. "I could manage a fund of that type."

Some G7 finance ministers have floated the possibility of the group helping Kyiv with as much as $50 billion in loans funded by frozen Russian assets. However, the controversial idea has not yet received full support from Western allies.

South Korea and Japan announce sanctions on Russia-North Korea weapons trade

South Korea and Japan announced a number of sanctions against individuals, ships and organizations linked to what the countries' governments allege is Russian purchasing of weapons from North Korea in violation of United Nations resolutions.

"Russia's procurement of arms from North Korea violates the relevant U.N. resolutions that completely prohibit the transfer of arms and related materials to and from North Korea," Yoshimasa Hayashi, Japan's chief cabinet secretary, told a press conference, according to Reuters.

South Korea's foreign ministry said it imposed sanctions on seven people from North Korea and two Russian ships involved in weapons trade between the two countries, who regard each other as allies.

Japan, for its part, said it imposed sanctions on one individual and 11 organizations, which it said included Russian groups supporting Russia's military operations in Ukraine, Reuters reported.

Romania declares Russian diplomat 'persona non grata'

Diplomats labeled persona non grata are usually recalled to their home nation.

The Romanian ministry said it communicated its decision to the Russian state. Moscow will respond to the measure, the Russian Ministry of Foreign Affairs told Russian state news agency Tass, according to a Google translation.

Russia unlikely to 'swallow the Western world whole,' Hungary's Orban says

Hungarian Prime Minister Viktor Orban downplayed the odds of Russia's success in a potential offensive against Western countries.

"I do not consider it logical that Russia, which cannot even defeat Ukraine, would all of a sudden come and swallow the Western world whole," Orban said in an interview on public radio, according to Reuters. "The chances of this are extremely slim."

Led by national conservative Orban, Hungary has declined providing military assistance to neighboring Ukraine since the start of Russia's full-fledged invasion, but extends humanitarian aid. Orban is widely seen as Russian President Vladimir Putin's closest ally among European nations.

"The Russian military is fighting a serious and difficult war with the Ukrainians," Orban said. "If the Russians were strong enough to wrestle down the Ukrainians in one go, they would have done so already."

Russia's war in Ukraine has now entered its second year, amid mounting concerns of a spillover of the conflict if Western countries intervene militarily.

G7 finance chiefs meet, with Ukraine loan on agenda

The Group of Seven of the world's advanced economies began a meeting of the finance and central banks' governors in Stresa, Italy — which holds the coalition's rotating presidency this year — with a view to discuss a potential loan to Ukraine.

Earlier this week, U.S. Treasury Secretary Janet Yellen told Sky News she saw the "possibility" that G7 nations could assist Ukraine with as much as $50 billion in loans linked to frozen Russian assets.

"I think that's a possibility. I believe it's important for the G7 to work together to show a united front and to show that we can generate meaningful resources to support Ukraine over the next several years," she said, according to Sky News.

"The Russian assets are not earning interest anymore, but they are generating returns for Euroclear. That alone could be given to Ukraine that would be repaid over several years by that flow of interest," Yellen added.

It remains to be seen whether G7 nations can strike consensus on such a loan and what final sum will be extended to support Kyiv's military effort.

France's defense ministry said it test-fired an updated version of a nuclear-capable missile, the ASMPA-R, for the first time on Thursday. The missile is built to be fired from a Rafale fighter jet.

The announcement came a day after Moscow declared it had started nuclear drills in territory that spans Russian and occupied Ukrainian land.

French Defense Minister Sebastien Lecornu said the missile was launched but without a warhead by a jet above French territory. In a Google-translated post on social media platform X, the minister thanked "all the forces, ministry teams and industrial partners involved" in the operation, which he said was "long-planned."

Seven dead in 'extremely brutal' Russian attack on Kharkiv, Ukrainian officials say

Seven people were killed and 16 were injured in Kharkiv following a Russian missile attack which damaged local residential, commercial and transport infrastructure, Ukrainian authorities said.

Russian troops targeted a civilian building in Kharkiv, northeastern Ukraine, around 10:30a.m. local time, and a fire broke out in a print shop, the regional police force said in a Google-translated Telegram post.

"In the Osnovyansk district of Kharkiv, enemy rockets hit the territory of the printing house. There was a large-scale fire. Seven people died, another 16 were injured. All the victims are employees of the enterprise. Debris analysis is ongoing," the prosecutor's office of Kharkiv said in a separate Google-translated Telegram update.

The institution added that Russian forces struck the Lyubotyn and Kharkiv cities with 15 S-300 and S-400 missiles launched from the Russian region of Belgorod, as part of the attack, the latest in a long series of strikes targeting Kharkiv.

CNBC could not independently verify developments on the ground.

Ukrainian President Volodymyr Zelenskyy characterized the incident as an "extremely brutal" offensive on the X social media platform and said that emergency services have arrived at the scene.

"Russian terrorists are taking advantage of Ukraine's lack of sufficient air defense protection and reliable capability to destroy terrorist launchers at their exact locations, which are close to our borders," he said.
