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 troops have reportedly seized a small village on the Russian-occupied eastern bank of Dneipr after crossing the river from the liberated city of Kherson, according to Russian accounts on Tuesday.

A small Ukrainian force has managed to dig in to the village of Dachi after making a landing there a few days ago and are trying to expand the beachhead. Ukrainian troops in small boats crossed the river and landed at the base of the ruined Antonivskiy Bridge, which they destroyed last year.

Russian military bloggers reported very heavy fighting on Tuesday, saying Russian airborne units have been trying unsuccessfully to dislodge the Ukrainians for the past four days. Russian aviation and heavy artillery have been firing on the Ukrainian position.

So far, the Russian side claims some 70 Ukrainian soldiers are dug in, covered by intense artillery fire from across the river. The Russian accounts say Ukraine is trying to move reinforcements across. Video released by Ukraine also shows a Russian APC being destroyed in the village of Oleshkjy, further south, indicating the bank south of Kherson is now contested.

Ukrainian troops have also managed to advance and liberate Rivnopil, a village on the Zaporozhzhia front, breaking through after more than two weeks of fighting. It's notable because the Russians had been fighting hard to hold it.

Taken together the advance there, the landing in Kherson and advances near Bakhmut are small signs the Ukrainian counteroffensive may be starting to pick up steam and the Russians are coming under growing pressure.

Travel restrictions remained in place on Sunday on the major M-4 highway near Moscow, according to Russia’s state-run media.

"According to the previously issued regional decisions, traffic restrictions remain in force on the M-4 Don highway near the Moscow Region and the Tula Region," the federal road agency said, according to TASS.

The security checkpoints had been put in place Saturday as a column of Wagner Group forces traveled toward Moscow. Roadblocks in southern Russia, including in Rostov-on-Don and the Krasnodar Region, were reportedly lifted.

"All previously imposed restrictions on highways have been lifted," TASS reported, citing a branch of the Russian Interior Ministry.
