The NATO summit in Vilnius showed that the NATO "alliance has finally returned to the schemes of the Cold War," the Russian Foreign Ministry said in a statement Wednesday.

"NATO consistently lowers the threshold for the use of force and strengthens the nuclear component in military planning," the statement added.

The Russian Foreign Ministry also noted NATO countries "promised to continue supplying more and more long-range weapons to Kyiv," saying they are doing so in order to "prolong the conflict."

Ukrainian President Volodymyr Zelenskyy said he received assurances that Ukraine will become a member of NATO and told reporters he believes it will happen "as soon as the security situation is stabilized," when answering questions after the conclusion of the NATO summit in Vilnius, Lithuania, on Wednesday.

When asked what Zelenskyy got out of the summit, he said he received "support from the leaders and an unambiguous statement that Ukraine will be in NATO."

"I believe that we will be in NATO as soon as the security situation is stabilized. In simple terms, the moment the war is over, Ukraine will definitely be invited to join NATO and Ukraine will definitely become a member of the alliance. I have not heard any other opinion today," Zelenskyy said.

Wagner forces are turning over weapons and military equipment to the Russian Armed Forces, the country's defense ministry said Wednesday.

More than 2,000 pieces of equipment and weapons were transferred to the Russian Armed Forces from Wagner forces, including hundreds of tanks, air defense systems, self-propelled artillery mounts, armored personnel carriers and more, the defense ministry said.

Among the equipment, dozens of units have never been used in combat before.

Russian forces also received more than 2,500 tons of various ammunition and about 20,000 small arms, the defense ministry said.

Separately, the Belarusian Interior Ministry has "begun talks seeking to invite Wagner Group members to train its troops," Interfax, a Russian news agency, reported Wednesday.

Ukrainian President Volodymyr Zelenskyy said his in-person meeting with U.S. President Joe Biden in Lithuania’s capital on Wednesday was "very good" and "powerful."

Zelenskyy took to Twitter after their meeting ended in Vilnius, saying it lasted "twice as long as planned" and "was as meaningful as it needed to be."

"If the protocol had not stopped the meeting, we would have talked even longer," he tweeted.

Zelenskyy said their meeting covered "all the topics," including long-term support for Ukraine, weapons, politics and NATO membership.

"We clearly see how to end this war with our common victory," he added. "Thank you, Mr. President!"

CIA Director Bill Burns said Yevgeny Prigozhin's mutiny showed the "corrosive effect" of President Vladimir Putin's war in Ukraine during remarks in England on Saturday.

"It is striking that Prigozhin preceded his actions with a scathing indictment of the Kremlin’s mendacious rationale for its invasion of Ukraine, and of the Russian military leadership’s conduct of the war," Burns said during a lecture to Britain's Ditchley Foundation. "The impact of those words and those actions will play out for some time, a vivid reminder of the corrosive effect of Putin’s war on his own society and his own regime."

Burns, who served as U.S. ambassador to Russia from 2005 to 2008, also noted how Russian disaffection will gnaw away at the Kremlin and that the CIA is taking this opportunity to step up its recruitment efforts in Russia.

"Disaffection with the war will continue to gnaw away at the Russian leadership, beneath the steady diet of state propaganda and practiced repression," Burns said. "That disaffection creates a once-in-a generation opportunity for us at CIA, at our core a human intelligence service. We're not letting it go to waste."
