Ukraine denies Russia's Wagner Group has taken control of Bakhmut

Russia's Wagner Group private army claimed on Saturday to have finally captured the eastern Ukrainian city of Bakhmut after the longest and bloodiest battle of the war butKyiv denied the city had fallen, though it called the situation there critical.

If confirmed, the announcement by Wagner leader Yevgeny Prigozhin that his troops had finally pushed the Ukrainians out of the last built-up area inside the city would amount to claiming Moscow's first big prize inmore than 10 months.

But any sense of victory for Russia appears likely to be fleeting. The announcement comes after a week in which Ukrainian forces have made their most rapid gains in six months on Bakhmut's northern and southern flanks, which Prigozhin has said put his troops inside the city at risk of encirclement.

Prigozhin, who has repeatedly denounced Russia's regular military for abandoning ground captured earlier by his men, said his own forces would now pull out of Bakhmut in five days to rest, handing the ruins of the city over to the regular military.

"Today, at 12 noon, Bakhmut was completely taken," Prigozhin said in a video in which he appeared in combat fatigues in front of a line of fighters holding Russian flags and Wagner banners. "We completely took the whole city, from house to house."

Ukraine says fighting continues

Ukrainian military spokesperson Serhiy Cherevatyi told Reuters: "This is not true. Our units are fighting in Bakhmut."

Ukraine's deputy defence minister, Hanna Maliar, reported "heavy fighting in Bakhmut. The situation is critical," she said on the Telegram messaging service.

"As of now, our defenders control some industrial and infrastructure facilities in the area and the private sector."

Mykhailo Podolyak, an adviser to Ukrainian President Volodymyr Zelenskyy, said, "This is not the first time Prigozhin has said, 'We seized everything and are dominating.'"

He also suggested that the Wagner chief's statement was aimed at drawing attention away from Zelenskyy's recent highly visible trips overseas, including to the Group of Seven summit in Japan on Saturday.

Whether the Ukrainian forces have left Bakhmut or not, they have been slowly pulling back inside it, to clusters of buildings on the city's western edge.

But meanwhile, to the north and south, they have made their most rapid gains in six months in the surrounding area, seizing swaths of territory from Russian troops.

Russia has acknowledged losing some ground around Bakhmut in the past week, while denying assertions by Prigozhin that the flanks around the city guarded by regular troops have collapsed.

Kyiv says its aim in Bakhmut has been to draw Russian forces from elsewhere on the front into the city, to inflict high casualties there and weaken Moscow's defensive line elsewhere ahead of a planned major counteroffensive.

"Wagner troops climbed into Bakhmut like rats into a mousetrap," Oleksander Syrskyi, commander of Ukraine's ground forces, told troops at the Bakhmut front this week.

Deepening rift between Russia, Wagner

British defence intelligence said on Saturday that Moscow appeared to be doubling down on the battle around Bakhmut, moving more troops there even though they were in short supply elsewhere. It was highly likely that Russia had deployed up to several battalions of scarce reserves to reinforce the Bakhmut sector, it said on Twitter.

The battle for Bakhmut has revealed a deepening split between Wagner a mercenary force that has recruited thousands of convicts from Russian prisons and the regular Russian military. For two weeks, Prigozhin has been issuing daily video and audio messages denouncing Russia's military leadership, often in expletive-laden rants.

Who is Yevgeny Prigozhin? CBC's David Common investigates what's known about the man leading the Wagner Group Russia's private mercenaries waging a bloody battle in Bakhmut, Ukraine.

In Saturday's video, he said that because of the "whims" of Russian Defence Minister Sergei Shoigu and Chief of Staff Valery Gerasimov, "five times more guys died than they should have." He thanked President Vladimir Putin, "that he gave us this chance and great honour to defend our motherland."

Moscow has long claimed that capturing Bakhmut would be a stepping stone towardadvancing deeper into the Donbas region it claims to have annexed from Ukraine. It has made it the principal target of a massive winter and spring offensive that failed to capture any significant ground elsewhere.

But Prigozhin has saidthat Bakhmut, a city of 70,000 people before the war, has little strategic significance, despite its huge symbolic importance because of the scale of losses in Europe's bloodiest ground battle since the Second World War.

Kyiv preparing counteroffensive

The grinding battle is reaching a climax just as Kyiv is preparing its counteroffensive, the next major phase in the war after six months during which it had kept its forces back on the defensive while weathering Russia's big offensive.

President Zelenskyy attended the G7 summit of major industrial powers in Japan on Saturday, winning pledges of support, including a signal from Washington that it would now back the training of Ukrainian pilots to fly F-16 warplanes.

For Zelenskyy, who left Ukraine for the first time following the February 2022invasion only last December, the summit demonstrated a newfound confidence in travelling the world to make his case in person. On his way to Japan, he stopped at an Arab summit in Saudi Arabia, just a week after a European tour to Rome, Berlin, Paris and London.

It provided a marked contrast with Putin, who has travelled outside the former Soviet Union only once since ordering the invasion a day trip to Tehran last July.

Putin's standing invitation to G7 summits once made it the G8, until he was kicked out after an earlier smaller-scale invasion of Ukraine in 2014, when Russia annexed Crimea.

He is now wanted by the International Criminal Court in The Hague for suspected war crimes, and was notably absent at a summit of former Soviet Central Asian states in China this week.
