The Russian military and security forces stopped what could have become a "civil war," President Vladimir Putin said on Tuesday.

"The Russian military in a difficult hour for the country stood in the way of turmoil, the result of which would be chaos," Putin said at an event for military units, adding that "the military and law enforcement officers of the Russian Federation actually stopped the civil war."

Defense Minister Shoigu, who the Wagner Group leader Yevgeny Prigozhin's had sought to have replaced, was present at Tuesday's ceremony.

The Russian Federal Security Service on Tuesday dropped the criminal case investigating the rebellion by Wagner Group leader Yevgeny Prigozhin and his forces.

The FSB said it closed the case because it has been established that participants stopped actions directly aimed at committing a crime.

The military in Belarus was ordered to "full combat readiness" during the Wagner Group's rebellion in neighboring Russia, President Alexander Lukashenko said.

Lukashenko, a longtime ally of Russian President Vladimir Putin, was said to have helped broker a deal to halt the choatic rebellion by Wagner leader Yevgeny Prigozhin.

"I will not hide, it was painful to watch the events that took place in the south of Russia," Lukashenko said Tuesday during brief remarks before a military presentation. "Not only me. Many of our citizens took them to heart. Because the fatherland is one."

The fatherland comment appeared to allude to Lukashenko's longstanding belief that Russia and Belarus share a special bond.

He added, "I gave all orders to bring the army to full combat readiness."

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.
