Latest Russia-Ukraine War News: Live Updates

KYIV, Ukraine — Russian forces are stepping up their efforts to make life unbearable for civilians across the occupied southern Kherson region, where power was cut on Sunday night and Ukrainian officials warned that Russian troops were mining critical infrastructure even as they dig in to fight for their last bridgehead west of the Dnipro River.

The battle for Kherson City — the only regional capital to be captured by Moscow since the invasion in late February — has been looming for months. A Ukrainian counteroffensive launched at the end of August has reclaimed over 100 towns and villages and steadily closed in on Kherson while also pounding Russian supply routes, command centers and ammunition depots far from the front.

As Ukrainian forces advanced, the Kremlin-appointed authorities for Kherson ordered the “evacuation” of all civilians last month — a move that Ukrainian officials said was less about saving lives and more about clearing space for newly mobilized Russian troops to occupy. Since then, Russian forces have been destroying critical infrastructure, shuttering essential services and looting the city, according to residents and Ukrainian officials.

Ukraine’s military said in an evening update on Monday that Russian forces were “taking measures to artificially create unacceptable living conditions for local residents, disconnecting electricity and communication.”

Petro, a 30-year-old who lives in the area, managed to get a message out late Sunday night, saying, “They are making a desert out of the right bank of Kherson.” Because of concerns about his safety, he communicated on the condition that his family name not be used.

“Today they blew up the power poles, so we have no light and no water,” Petro added.

While state media in Russia said that Ukrainian shelling had damaged the power lines, Yaroslav Yanushevych, the exiled Ukrainian head of the Kherson regional military administration, blamed Russian troops.

“It is impossible to quickly repair the power lines due to a lack of specialists and equipment,” he said Sunday night. “In addition, Russian invaders will not allow this to be done.”

The Russian forces have also placed mines around water towers in Beryslav, Mr. Yanushevych said, referring to a town less than 50 miles from Kherson City and just north of a critical dam.

Russian forces seized the road over that dam, next to the town of Nova Kakhovka, in the first days of the war, and it is the main artery across the Dnipro River still under the control of Russian forces. If Ukraine regains control of the area, they could prevent thousands of Russian soldiers from escaping.

Ukrainian forces are still meeting fierce resistance as they continue battling Russian troops arrayed some 30 miles to the north of the dam.

Ukrainian and Russian officials have accused each other of planning to blow up the dam. But military analysts have said that doing so would be logistically challenging and would not serve either army’s interests because it would cause flooding and destruction on both sides of the Dnipro.

Still, Ukraine’s nuclear regulator on Monday ordered an urgent review of the safety risks upriver at the Zaporizhzhia Nuclear Power Plant if the dam were to be damaged.

The Ukrainian military high command said on Monday that the destruction of critical infrastructure was part of a coordinated campaign to undermine its forces and warned that Moscow had dispatched propagandists “to shoot videos in the city on the topic of the alleged destruction of the civilian population.”

Top government officials in Kyiv have also said that Moscow might be trying to create the illusion of leaving Kherson to lure Ukrainian forces into brutal urban combat. On Monday, the Ukrainian military said that it still had seen no evidence that Russian forces were preparing to abandon Kherson.

But the Ukrainian authorities warned that Russian forces were stepping up the hunt for people helping to direct military strikes. The Russians have “intensified raids and filtration measures among the local population,” the National Resistance Center, a government agency supporting resistance efforts in occupied areas, said on Monday.

So-called filtration centers were set up by Russia to temporarily detain and screen Ukrainians and identify anyone perceived to pose a threat to Russia’s occupation efforts. In July, U.S. Secretary of State Antony J. Blinken said that Russian authorities had  “forcibly deported” between 900,000 and 1.6 million Ukrainian citizens to Russian territory,

The National Resistance Center said that it was aware of “dozens of detainees” who were being taken to camps, saying that once there, they would be interrogated and tortured. The claim could not be independently verified.
