Ukrainian forces attacked Russia’s hold on the southern city of Kherson on Thursday while fighting intensified in the country’s east.

The battles came amid reports that Moscow-appointed authorities in the city have abandoned it, joining tens of thousands of residents who fled to other Russia-held areas.

Ukrainian forces were surrounding Kherson from the west and attacking Russia’s foothold on the west bank of the Dnieper River, which divides the region and the country.

As the battles unfolded, Russian President Vladimir Putin said that Moscow has no intention to use nuclear weapons in Ukraine.

“We see no need for that,” Mr Putin said at a conference of international foreign policy experts. “There is no point in that, neither political nor military.”

The Russian leader also sought to cast the conflict as part of efforts by the West to secure global domination.

He accused the US and its allies of trying to dictate their terms to other nations in a “dangerous and bloody” domination game.

Meanwhile, Russia warned that Moscow could target Western commercial satellites used for military purposes in support of Ukraine, and a Foreign Ministry spokeswoman accused the United States of pursuing “thoughtless and mad” escalation.

Spokeswoman Maria Zakharova argued that Washington should take an approach more like it did during the Cuban Missile Crisis in 1962, when the Cold War superpowers stepped back from the brink of nuclear confrontation.

“The more the US is drawn into supporting the Kyiv regime on the battlefield, the more they risk provoking a direct military confrontation between the biggest nuclear powers fraught with catastrophic consequences,” Ms Zakharova said.

Ukraine has pushed ahead with an offensive to reclaim the Kherson region and its capital of the same name, which Russian forces captured during the first days of a war now in its ninth month.

More than 70,000 residents from the Kherson city area have evacuated in recent days, the region’s Kremlin-installed governor, Vladimir Saldo, said on Thursday.

Members of the Russia-backed regional administration also fled, the deputy governor, Kirill Stremousov said.

Ukrainian President Volodymyr Zelensky described reports of Russian troops’ possible withdrawal from the city as disinformation.

“I don’t see them fleeing from Kherson,” Mr Zelensky said in an interview with Italy’s Corriere della Sera newspaper.

“This is an information attack, so that we go there, transfer troops from other dangerous directions there.”

Mr Zelensky also dismissed as “theatre” recent attempts by local Kremlin-backed officials to persuade the city’s civilian residents to relocate deeper into Russian-held territory ahead of the Ukrainian advance.

“Their most trained soldiers are in position. We see this and do not believe them,” Mr Zelensky said.

In eastern Ukraine, Russian forces continued to bombard the city of Bakhmut in the Donetsk region, making slow gains toward the centre.

The deputy head of Russia’s delegation at a UN arms control panel, Konstantin Vorontsov, described the use of US and other Western commercial satellites for military purposes during the fighting as “extremely dangerous”.

“The quasi-civilian infrastructure could be a legitimate target for a retaliatory strike,” Mr Vorontsov warned.

As they have all month, Russian forces carried out attacks on Ukraine’s energy infrastructure, which have caused increasing worry ahead of winter.

A Russian drone attack early on Thursday hit an energy facility near the capital of Kyiv, causing a fire, said Kyiv regional governor Oleksiy Kuleba. He said the latest attacks inflicted “very serious damage”.

“The Russians are using drones and missiles to destroy Ukraine’s energy system ahead of the winter and terrorize civilians,” Mr Kuleba said in televised remarks.

Mr Kuleba announced new rolling blackouts and urged consumers to save power. He said authorities were still pondering how to restore power.

Kyrylo Tymoshenko, deputy head of Ukraine’s presidential office, said rolling blackouts would also be introduced in the neighbouring Chernihiv, Cherkasy and Zhytomyr regions.

Mr Zelensky has said that Russian attacks have already destroyed 30% of the country’s energy infrastructure.

In a likely response to Russia’s attacks on Ukrainian infrastructure, a power plant was attacked just outside Sevastopol, a port in the Russian-annexed region of Crimea.

The plant suffered minor damage in a drone attack, according to city leader Mikhail Razvozhayev. He said electricity supplies were uninterrupted.

Crimea, a region slightly larger than Sicily, was annexed by Russia from Ukraine in 2014. It has faced drone attacks and explosions amid the fighting in Ukraine.

In a major setback for Russia, a powerful truck bomb blew up a section of a strategic bridge linking Crimea to Russia’s mainland on October 8.

A senior Ukrainian military officer accused Russia of planning to stage explosions at the Zaporizhzhia Nuclear Power Plant and blame them on Ukraine in a false-flag attack.

General Oleksii Gromov, the chief of the main operational department of the Ukrainian military’s general staff, pointed to Moscow’s repeated unfounded allegations that Ukraine was plotting to detonate a radioactive dirty bomb as a possible signal that Moscow was planning explosions at the plant, Europe’s largest nuclear power station.

Russia took control of the Zaporizhzhia plant in the opening days of the invasion. Russia and Ukraine have accused each other of attacking the plant, which had its reactors shut down following continuous shelling.

Gen Gromov also charged on Thursday that Russian forces may have set off explosions at residential buildings in the city of Kherson before retreating from the city.
