Russia-Ukraine updates: US sanctions Russian military shipbuilder, diamond miner

Over the last 24 hours, the Pentagon has seen less than 20% of the Russian troops that had been around Kyiv "reposition" northward, Pentagon spokesman John Kirby said.

Kirby said Russian claims that they are withdrawing troops to deescalate fighting amid peace talks with Ukraine is just "spin."

Kirby said he was intentionally using the term "reposition" instead of withdrawal to describe the movement of Russian forces "because the way it's being spun by the Ministry of Defense is that they're pulling back and they're trying to deescalate and depressurize the situation. And we just don't believe we haven't seen any evidence of that."

Kirby said the U.S. assesses that the Russians are instead “going to refit these troops, resupply them, and then probably ... employ them elsewhere in Ukraine."

Shelling is continuing in Chernihiv and the suburbs of Kyiv, one day after the Kremlin said Russian operations near the two cities would be "scaled down dramatically."

In Chernihiv, in northern Ukraine, Gov. Viacheslav Chaus said shelling lasted all night and that civilian targets were being destroyed, including shopping malls and libraries. Local authorities said at least one civilian was killed and six were wounded.

Activity was relentless Wednesday in Irpin, near Kyiv, and bombardments in the suburbs have continued into the night.

Oleksandr Motuzyanyk, a spokesperson for Ukraine's Ministry of Defense, said Wednesday that Russian troops have not completely abandoned attempts to capture or at least surround Kyiv and Chernihiv. The General Staff of the Armed Forces of Ukraine said some Russian military units are being relocated but that there's no mass withdrawal of troops.

President Joe Biden and Ukrainian President Volodymyr Zelenskyy spoke on the phone from 11:08 a.m. ET to 12:03 p.m. ET, according to the White House.

Biden said the U.S. will provide Ukraine with "$500 million in direct budgetary aid," according to a White House readout. The $500 million is for financial assistance that Ukraine can use for budgetary expenses such as paying salaries and maintaining government services, according to the White House.

"The leaders discussed how the United States is working around the clock to fulfill the main security assistance requests by Ukraine, the critical effects those weapons have had on the conflict, and continued efforts by the United States with allies and partners to identify additional capabilities to help the Ukrainian military defend its country," the White House said.

Zelenskyy in a tweet said they "talked about specific defensive support, a new package of enhanced sanctions, macro-financial and humanitarian aid."

Ukraine warned Norway on Wednesday that Russian forces have "amassed in the Arctic region" and will ultimately pose a threat to Europe.

"I think you are experiencing new risks near your border with Russia," Ukrainian President Volodymyr Zelenskyy said in an address to Norwegian lawmakers via video link from Kyiv. "A number of Russian troops that has no normal explanation has already been amassed in the Arctic region. For what? Against whom?"

"The future of Europe -- the whole continent from north to south, from west to east -- is being decided right now," he added. "On our land, on Ukrainian soil, in Ukrainian air, in Ukrainian sea. So that your soldiers do not have to defend NATO's eastern flank, so that Russian mines do not drift to your ports and fjords, so that your people do not have to get used to the sound of air alarms and so that Russian tanks are not amassed at your border, we must stop the aggression of the Russian Federation together and only together."

Zelenskyy said Russian forces are continuing to carry out relentless and indiscriminate attacks on his country. Although Ukrainian troops are holding off Russian advances, he warned that "the columns of Russian armoured vehicles are not decreasing."

"There are no forbidden targets for Russian troops. They attack everything," he told Norwegian lawmakers. "Ukraine's losses are enormous."
