CNN — 

A Ukrainian offensive is “taking place in several directions,” Deputy Defense Minister Hanna Maliar told Ukrainian television on Monday, heightening speculation that a major push by Kyiv to recapture land held by Russia’s occupying forces could be getting underway.

“It is not only about Bakhmut. The offensive is taking place in several directions. We are happy about every meter. Today is a successful day for our forces,” she said.

Recent weeks have seen Ukraine’s military stepping up shaping operations – attacks on Russian targets like fuel depots and weapons dumps far behind frontlines – which typically precede a major advance by ground forces. But government officials in Kyiv have been at pains to say the start of any counteroffensive would not be announced.

Both Ukraine and Russia have engaged in intense information campaigns to sway public opinion and mislead their opponents about their battle plans.

Maliar’s comments came after the Russian Defense Ministry claimed its troops resisted a “large-scale” attack from Ukrainian forces in the eastern Donetsk region. The Russian military claimed in a statement to have killed 250 Ukrainians and destroyed armored vehicles used in the assault, but provided scant evidence.

Moscow is known to make inflated claims about Ukrainian losses. CNN has been unable to independently verify the claim.

A spokesperson for the Ukraine Armed Forces, Bohdan Senyk, told CNN that Ukraine does “not have information” on a purported “large-scale offensive” in Donetsk.

In a post on its official Telegram feed, the Russian Defense ministry said the assault took place at “five section of the front in the southern Donetsk direction.”

The ministry claimed the goal of the Ukrainian operation was “to break through” Russian defenses in what it considered to be “the most vulnerable area of the front.”

At the time of the attack, Russia’s top general Valery Gerasimov “was at one of the forward command and control posts,” the statement added.

Gerasimov, who is chief of Russia’s General Staff, was put in overall command of Russian military operations in Ukraine early this year. He has come under public criticism from the head of the Russian private military company Wagner for supposedly running the war from a comfortable office.

Further south, a Russian-appointed official in Zaporizhzhia said Ukrainian troops were attempting to break through a defense line to reach the coast of the Sea of Azov.

“The goal of the [Ukraine Armed Forces] militants is to reach the Azov Sea coast and cut the land corridor,” Vladimir Rogov said, according to Russian state media outlet RIA Novosti.

He claimed that Ukrainian troops have increased the intensity of their shelling, and fired Storm Shadow missiles. “They are launched in large quantities, which means Ukrainian militants and terrorists have ammunition in sufficient quantity.”

Rogov said he did not think a full-scale counteroffensive had begun.

‘Offensive actions’

In a Monday Telegram post, Maliar said the country’s troops were “carrying out offensive actions” on the eastern front and had “advanced in several directions” around the city of Bakhmut: near the settlements of Orikhovo-Vasylivka and Paraskoviivka to the north, and near Ivanivske and Klishchiivka to the southwest.

Serhii Cherevatyi, spokesman for the Eastern Grouping of the Ukrainian Armed Forces, also spoke of “an offensive assault” by the Ukrainians “on the southern and northern flanks of Bakhmut” on national TV on Monday.

“These actions were successful,” Cherevatyi said. “Despite the enemy’s fierce resistance, our airborne assault and mechanised units managed to advance along the Siverskyi Donets-Donbas Canal in the direction of Klishchiivka, Orikhovo-Vasylivka, Zaliznianske, and Bohdanivka to a distance of 300 meters to 1 km in various parts of the frontline.”

CNN cannot verify the battlefield reports.

It comes after Maliar and other officials posted a social media video urging silence over any potential news of a counteroffensive.

The video shows several soldiers in full combat gear putting a finger to their lips and saying “shhh” followed by the text: “Plans love silence. The beginning [of the counteroffensive] will not be announced.”

Ukrainian President Volodymyr Zelensky praised troops fighting around the embattled city of Bakhmut during his nightly address, saying: “I am grateful to every warrior, to all our defenders, who provided us today with the news we have all been waiting for in the Bakhmut direction. Well done, warriors!”

Days before, Zelensky told the Wall Street Journal (WSJ) that Kyiv was “ready” to launch the long-awaited military maneuvers.

“I think that, as of today, we are ready to do it. We would like to have certain things, but we can’t wait for it for months,” Zelensky said in an exclusive video interview published Saturday.

The president said he believed the counteroffensive will be successful but was not sure how long it will take.

“Everyone knows perfectly well that any counteroffensive in the world without control in the skies is very dangerous. Imagine what a military man feels, knowing he does not have a ‘roof’ and he can’t understand how neighboring countries have that,” Zelensky said about his dogged campaign for allies to supply Ukraine with F-16 fighter jets.

According to the WSJ, Zelensky acknowledged Russia’s superiority in the skies, adding that a lack of protection against Moscow’s air power means “a large number of soldiers will die” during the counteroffensive.

“If everybody knows we need the protection for our skies, then what’s the issue with [giving us] the modern jets? What is the issue?” he implored.

The Ukrainian leader has spent months courting Western allies to provide Kyiv with fighter jets and weapons to help control the skies and help limit the number of casualties to Ukrainian fighters during any potential counteroffensive.

Russian advances are areas where Russian forces have operated in or launched attacks, but they do not control them. “Claimed” areas are where sources have said control or counteroffensives are occurring, but ISW cannot corroborate nor demonstrate them to be false.

Earlier this week, Jake Sullivan – US President Joe Biden’s national security adviser – said Washington believed the counteroffensive would help Kyiv retake “strategically significant territory.”

“Exactly how much, in what places – that will be up to developments on the ground as the Ukrainians get this counteroffensive underway,” Sullivan told CNN’s Fareed Zakaria. “But we believe that the Ukrainians will meet with success in this counteroffensive.”
