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.

Ukrainian technicians have started repairing damaged power lines in an attempt to restore external electricity supplies to the site of the Russian-controlled Chernobyl nuclear power plant that were entirely cut earlier in the week, according to International Atomic Energy Agency Director General Rafael Mariano Grossi.

Ukraine’s regulatory authority said work began Thursday and technicians had succeeded in repairing one section, but off-site electrical power was still down, indicating there was still damage in other places.

Emergency diesel generators have been providing backup power to the site since Wednesday, and the regulator has reported that additional fuel had been delivered to the facility, the IAEA said.

The regulator lost communications with the site on Thursday and, as a result, it cannot provide information to the IAEA about the radiological monitoring at the facility, according to Grossi.

The regulator is still receiving information about the situation there through senior off-site management of the plant, Grossi said.

The plant's disconnection from the grid will not have a critical impact on essential safety functions at the site, however, staff is facing increasingly difficult conditions.

At least 211 technical personnel and guards have been living at the site for more than two weeks, and there is concern about the availability of food reserves, the regulator said.

The IAEA said eight of the country’s 15 reactors remained operating. Radiation levels at the locations were normal, the IAEA said.
