Russian forces in retreat near Bakhmut, Ukraine and Wagner say

NEAR BAKHMUT, Ukraine — The Ukrainian military and Russia's Wagner private army both reported further Russian retreats on the outskirts of Bakhmut on Thursday, as Kyiv pressed on with its biggest advance for six months ahead of a planned counteroffensive.

Ukrainian troops near the front line said Russia was bombarding access roads to slow the Ukrainian assault, which has shifted momentum after months of slow Russian gains in Europe's deadliest ground combat since World War Two.

"Now, for the most part, as we have started to advance, they are shelling all the routes to front positions, so our armored vehicles can't deliver more infantry, ammunition and other things," said Petro Podaru, commander of a Ukrainian artillery unit.

Ukraine's military, which has been cautious so far in reporting gains in the area, said troops had advanced in places by more than a mile. Its forces had been on the defensive for half a year, weathering a huge winter and spring offensive by Moscow that saw only slow gains.

"Despite the fact that our units do not have an advantage in equipment ... and personnel, they have continued to advance on the flanks, and covered a distance of 150 to 1,700 meters [1.1 miles]," military spokesperson Serhiy Cherevatyi said in televised comments.

Ukraine's gains have been accompanied by a deepening public split within Russia's forces between Wagner, which has led the Bakhmut campaign, and the regular Russian military.

The blasted ruins of Bakhmut, described by both sides as a "meat grinder," would be Moscow's only prize for its huge winter offensive that failed elsewhere along the front.

Kyiv says it has launched local advances around Bakhmut as a prelude to an upcoming big counteroffensive that it hopes will turn the tide against Russia's 15-month-old invasion.

Wagner boss Yevgeny Prigozhin says his forces inside Bakhmut itself are still advancing, on the cusp of pushing Ukrainian troops out of their last foothold in the built-up area on the city's Western outskirts.

But he accuses commanders of Russia's regular forces of abandoning vital ground on the flanks north and south of the city, raising the risk of troops inside being encircled. Since last week Prigozhin has released daily messages denouncing the regular military brass.

"Unfortunately, units of the Russian Defense Ministry have withdrawn up to 570 meters (1,880 feet) to the north of Bakhmut, exposing our flanks," Prigozhin said in his latest voice message on Thursday.

"I am appealing to the top leadership of the Ministry of Defense—publicly—because my letters are not being read," Prigozhin said, addressing Defense Minister Sergei Shoigu and Chief of the General Staff Valery Gerasimov.

"Please do not give up the flanks."

The Russian defense ministry has acknowledged some withdrawals from positions near Bakhmut over the past week but denies Prigozhin's assertions that flanks are crumbling, or that it has withheld ammunition from Wagner.

Falling into 'the mousetrap'

Ukraine says its tactic around Bakhmut is deliberately to draw Russian forces into the city, so as to weaken Russia's front line defenses elsewhere ahead of Kyiv's planned counterassault.

"Wagner troops climbed into Bakhmut like rats into a mousetrap," Oleksander Syrskyi, commander of Ukraine's ground forces, told troops at the Bakhmut front in video he released this week on social media.

"Using the principle of active defense, we resort to counteroffensive actions in some directions near Bakhmut. The enemy has more resources, but we are destroying his plans."

With Kyiv's counteroffensive looming, Russia has resumed countrywide missile and drone strikes across Ukraine this month after a near two-month lull. Waves of attacks now come several times a week, the most intense pace of the war.

In the latest on Thursday, air raid sirens sounded across most of the country overnight, black smoke filled the sky over Kyiv and one person was reported killed in the southern city of Odesa. Ukraine said it had shot down 29 of 30 incoming missiles. Moscow claimed to have hit its military targets.

Russia has also been experiencing attacks and explosions both in Ukrainian territory it controls and in Russian territory near the border. Officials in Russian-occupied Crimea reported a freight train had been derailed overnight by "interference." Kyiv never confirms any role in incidents there.

On the diplomatic front, leaders of the G7 group of big developed countries were meeting in Japan where they are expected to unveil tighter measures to close off Russia's opportunities to bypass financial sanctions.

On Wednesday, Moscow agreed to a two-month extension of a deal safeguarding exports of Ukrainian grain from Black Sea ports despite the war. Russia had threatened to abandon the deal unless it received additional guarantees protecting its own grain and fertilizer exports.

Kremlin spokesman Dmitry Peskov said Moscow had agreed to the extension although its concerns were not yet fully addressed. "A certain part of the way has been traveled—there are results—but not definitive ones. We will try to solve this problem definitively within these 60 days," he said. — Reuters
