Russia-Ukraine updates: Russian missile strikes hit multiple Ukrainian cities

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."

Russian President Vladimir Putin offered his first public remarks after the Wagner Group attempted to march to Moscow and overthrow the government.

In a pre-recorded video statement, Putin thanked the Russians for their endurance, solidarity and patriotism during the ordeal and claimed that any blackmail attempt was doomed to fail.

Putin said an armed rebellion would have been suppressed.

"The organizers of the rebellion, betraying their country, their people, betrayed those who were drawn into the crime. They lied to them, pushed them to death, under fire, to shoot at their own," Putin said.

The Russian president noted that the majority of Wagner fighters were "patriots."

"I thank those soldiers and commanders of the Wagner Group who made the only right decision," Putin said. "They did not go to fratricidal bloodshed, they stopped at the last line."

Putin offered Wagner Group members who participated in the rebellion the option of joining the defense ministry or other law enforcement agencies or returning home.
