The Biden administration announced it's levying sanctions against Russia's largest military shipbuilding and diamond mining companies on Thursday night.

The move blocks their access to the U.S. financial system as the United States looks to exact more economic pain on Russian President Vladimir Putin for the invasion of Ukraine.

Alrosa is the world's largest diamond mining company and accounts for about 90% of Russia's diamond mining capacity, according to the U.S. Treasury Department. Alrosa generated over $4.2 billion in revenue in 2021. Diamonds are one of Russia's top 10 non-energy exports by value.

The State Department also said it was blacklisting the United Shipbuilding Corporation, as well as its subsidiaries and board members. The moves against the two state-owned companies come a day after the U.S. announced it was targeting the two adult daughters of Putin, two of Russia's largest banks and banning new American investment in Russia.

A Fox News reporter severely injured in a shelling in Ukraine last month that killed two other journalists tweeted for the first time Thursday to update his condition and pay tribute to his colleagues.

Fox News State Department correspondent Benjamin Hall was injured in an attack in Gorenka, outside Kyiv, on March 14. Ukrainian producer and fixer Oleksandra "Sasha" Kuvshynova and Fox News cameraperson Pierre Zakrzewski were both killed after incoming fire hit their car.

"Its (sic) been over three weeks since the attack in Ukraine and I wanted to start sharing it all," Hall said. "But first I need to pay tribute to my colleagues Pierre and Sasha who didnt (sic) make it that day. Pierre and I traveled the world together, working was his joy and his joy was infectious."

Hall also shared a Fox News segment in which a Ukrainian parliament member paid tribute to Kuvshynova.

The journalist, who was initially treated at a German hospital before being transferred to Brooke Army Medical Center in San Antonio, detailed his injuries in another tweet.

"To sum it up, I've lost half a leg on one side and a foot on the other. One hand is being put together, one eye is no longer working, and my hearing is pretty blown… but all in all I feel pretty damn lucky to be here - and it is the people who got me here who are amazing!" he said.

Ukrainian President Volodymyr Zelenskyy said the situation in Borodyanka is "much worse" than what Ukrainians have found in other towns where Russian forces have departed.

In his daily address, Zelenskyy said there are "even more victims of the Russian occupiers," in Borodyanka.

Zelenskyy has warned in previous statements that they expected to find many more victims in Borodyanka than the number discovered so far in Bucha.

He also said the United Nations General Assembly's decision to suspend Russia's membership from the Human Rights Council was "quite logical, quite rightly."

"Russia has had nothing to do with the concept of human rights for a long time ... maybe someday that will change," Zelenskyy said.

The European Union approved a fifth round of sanctions against Russia for its invasion of Ukraine on Thursday, officials said.

The "substantial" package extends sanctions to "oligarchs, Russian propaganda actors, members of the security and military apparatus and entities in the industrial and technological sector linked to the Russian aggression against Ukraine," according to the French Presidency of the Council of the EU.

It also includes a ban on coal imports from Russia, an embargo on arms to Russia and a freeze on the assets of several Russian banks, among other sanctions.

The United States is supporting a multinational team of independent war crimes investigators, including American experts, that are working with Ukraine's prosecutor-general on a probe of alleged Russian war crimes, U.S. State Department spokesperson Ned Price said on Monday.

The team is working in Eastern Europe, but not in Ukraine itself, Price said. He said the team is collecting, preserving and analyzing evidence with a view toward prosecutions and other forms of holding Russia accountable, Price said.

The United States is also supporting the effort through funding for non-government organizations that are part of the effort, Price said. He said he could not provide further details, including how many Americans are involved or how much funding is being allocated.

At the start of his briefing on Monday, Price noted the horrific reports from Bucha, Ukraine, and other towns outside of the capital of Kyiv, describing reports of "civilians, many with their hands tied, apparently executed in the streets, others in mass graves."

"We are seeing credible reports of torture, rape and civilians executed alongside their families," Price said. "There are reports and images of a nightmare litany of atrocities, including reports of land mines and booby traps left behind by Putin's forces to injure even more civilians and slow the stabilization and recovery of devastated communities after they failed in their objective and withdrew."

U.S. Secretary of State Antony Blinken will discuss the reported atrocities with his NATO foreign minister counterparts during the Western military alliance's spring meeting this week, Price said.

President Joe Biden said earlier Monday that he is calling for more sanctions to be imposed on Russia in light of the reports from Bucha.

"We're continuously tightening sanctions and preparing for additional sanctions, jointly with our allies and partners," Price said.
