The U.S. announced additional sanctions targeting the Wagner Group, specifically going after gold companies and a Russian man it says are illicitly funding the Wagner Group’s operations in Ukraine and Africa.

Central African Republic based companies Midas Resources SARLU and Diamville SAU, Dubai based company Industrial Resources General Trading and Russia based company Limited Liability Company, re connected to Wagner’s leader Yevgeny Prigozhin, who is already subject to U.S. sanctions along with numerous other entities linked to the Wagner Group, according to the Department of the Treasury’s Office of Foreign Assets Control.

Andrey Nikolayevich Ivanov, a Russian national, and an executive in the Wagner Group, allegedly worked closely with Prigozhin’s entity Africa Politology and senior Malian government officials on weapons deals, mining concerns, and other Wagner Group activities in Mali, OFAC said.

"The Wagner Group funds its brutal operations in part by exploiting natural resources in countries like the Central African Republic and Mali," Brian Nelson, the U.S. under secretary of the treasury for terrorism and financial intelligence, said in a written statement. "The United States will continue to target the Wagner Group’s revenue streams to degrade its expansion and violence in Africa, Ukraine, and anywhere else."

Ukraine has recaptured approximately 300 square kilometers during the summer counteroffensive so far, United Kingdom Defense Secretary Ben Wallace said Tuesday.

The gains represent more territory than Russia seized during its winter offensive in 2022, Wallace told Parliament.

Belarus President Alexander Lukashenko provided more details about his alleged role in negotiations between Wager Group leader's Yevgeny Prigozhin and Russian President Vladimir Putin following the PMC's rebellion.

Lukashenko claimed Prigozhin abandoned his demands, including the resignation of Shoigu, after they talked.

"[Prigozhin] told me 'Alexander Grigoryevich, I will not demand from the president that he give up Shoigu and Gerasimov, and I will not even ask for a meeting,' I say, 'Well, that’s good. This is a very good move,'" Lukashenko claimed.

Lukashenko said that Wagner forces could join the Belarusian army but said that he won't built camps for Wagner's troops in his country.

"We don't need to open any Wagner recruitment points," he said.

Belarus President Alexander Lukashenko said on state media Tuesday that Wagner Group leader Yevgeny Prigozhin arrived in his country earlier in the day.

Lukashenko claimed on state media that "security guarantees" Russian President Vladimir Putin promised to Prigozhin were provided.

"Yes, indeed, he is in Belarus today. As I promised, if you want to stay with us for a while and so on, we will help you," Lukashenko said.

A senior U.S. official confirmed to ABC News that Prigozhin is in exile in Belarus, surrounded by a security force of his own Wagner mercenaries.

Ukrainian Armed Forces have yet to reach their "full potential," but two top generals exclusively told ABC News the counteroffensive is "going to plan" despite concerns from Western analysts that Ukraine is not making enough progress.

Gen. Oleksandr Tarnavskyi, who is leading the counteroffensive in the south, told ABC News' chief global affairs correspondent Martha Raddatz that the situation is "stable."

"The main thing is that we haven’t reached our full potential," Tarnavskiy said.

Ukrainian troops launched the counteroffensive a month ago, attacking on multiple axes on the southern frontline in Zaporizhzia using Western-supplied vehicles. Ukraine succeeded in piercing Russian lines at two points, liberating a string of villages, but has since been locked in ferocious fighting

Gen. Oleksandr Syrskyi, commander of the Ukrainian ground forces, told Raddatz that last month's failed rebellion by the Putin-backed PMC, the Wagner Group, wouldn't impact the fighting on the ground.

"It would be better for us if there were some negative consequences in Russia itself, but it doesn't matter for me," he said.

Asked if he was confident of retaking the key city of Bakhmut, Syrskyi said, "Yes, of course. I’m sure."

Both sides have suffered heavy casualties, according to Western officials, particularly in the south where Russia has so far conducted "relatively effective defensive operations" in the southeastern Zaporizhzhia province, the U.K. Ministry of Defense reported.

"The enemy is suffering eight times or even 10 times higher losses, especially with the number of killed troops," Syrksyi said.
