Russian drones hit Ukraine's power grid, warehouses, a food warehouse, a home-improvement store, and a farm overnight on 9 October, Ukrainian officials and emergency services reported. The strikes triggered emergency power cuts in Kyiv and other regions and killed at least three people across the country.

As Russia continues its daily terror attacks, it has likely begun its winter strike campaign early, aiming to make civilian life in Ukraine unbearable, ISW assessed. Those strikes now reach beyond the grid to the businesses that store and sell goods, adding to damage Ukraine's Economy Ministry expects to reach up to $10 billion this year.

Power cut in Kyiv and other regions

Russia launched 136 drones overnight, 93 of them jet-powered, Ukraine's Air Force said. Air defenses downed or suppressed 114. Drones hit eight locations, and debris fell at seven more.

DTEK, Ukraine's largest private energy company, introduced emergency power cuts on Kyiv's right bank and in the Bucha and Vyshhorod districts on the grid operator's orders. Ukrenergo, the national grid operator, imposed emergency outages in some regions, citing the strain Russian attacks put on the system. Planned schedules were suspended there. Hourly cuts across parts of Ukraine had already been set for the whole day.

The cuts came a day after a Russian strike knocked out several grid elements supplying Kyiv, leaving many consumers without power. Russia has sharply stepped up attacks on Ukraine's energy system in recent weeks, deliberately targeting power lines and transformers, Ukraine's Energy Ministry said.

Warehouses and a store

In the Bucha district of Kyiv Oblast, Russia hit warehouses and injured three people, Ukraine's State Emergency Service said. One was hospitalized. Rescuers were searching for a woman who may be under the rubble.

In Odesa, a strike damaged the roof of a warehouse storing food and started a fire, the region's emergency service reported. In the south of the oblast, Russia damaged buildings at holiday resorts and destroyed a café.

Near Chernihiv, Russia hit a site just outside the city after 03:00, the city council said. A Suspilne correspondent at the scene reported that a drone hit the Epicenter store, part of a large Ukrainian home-improvement chain. Russian forces also struck a farm in the Kulykivka community. No one was hurt in Chernihiv Oblast.

Russia has already destroyed more than two-fifths of Ukraine's modern warehouse space.

Three killed overnight

In Zaporizhzhia, Russia struck near an apartment building, killing a man, the Zaporizhzhia Oblast administration said. The number of injured rose to nine, including a 14-year-old girl, regional prosecutors said. One strike landed near an after-school education center.

In Ivano-Frankivsk, falling drone debris started a fire, and a man born in 1959 was killed, Ivano-Frankivsk Oblast head Svitlana Onyshchuk said.

In Shyroka Balka, Kherson Oblast, a Russian drone dropped explosives on a house at about 06:20, killing a 74-year-old woman and injuring a 68-year-old man, regional prosecutors reported.

Russia injured three women in a Kharkiv suburb, Kharkiv Oblast head Oleh Syniehubov said. In the Nikopol district, a 24-year-old woman was injured, Dnipropetrovsk Oblast head Oleksandr Hanzha said.

Poland scrambled military aircraft as Russia struck targets in western Ukraine, its Operational Command said.

The past day's toll

Over the past 24 hours, Russia killed two people and injured 18 in Zaporizhzhia and the Zaporizhzhia district, regional council head Ivan Fedorov said. In Sumy Oblast, one man was killed and 14 people were injured, including two 12-year-old boys, the regional administration reported.

In Kherson Oblast, four people were injured, including a child, Kherson Oblast head Oleksandr Prokudin said. In Mykolaiv Oblast, a Russian drone injured two children aged three months and one year, acting oblast head Heorhii Reshetilov said. Three people were injured in Kharkiv Oblast, Syniehubov reported.

In Donetsk Oblast, Russia killed 35 people and injured 25 on 8 October, Donetsk Oblast head Vadym Filashkin said. Thirty-two of them died in Kramatorsk, most in a Russian bomb strike on two passenger buses.

Ukrainian forces are advancing east of Sloviansk and Kramatorsk, and even Russian milbloggers now acknowledge it, the Institute for the Study of War (ISW) said on 8 October. The gains may follow months of groundwork like the one that preceded Operation Vivaldi near Lyman, which Ukraine says returned 176 km² to its control. Russian commentators are already doubting that Moscow can reach the two cities.

Russia's years-long push on the Fortress Belt, the chain of cities anchoring Ukraine's defense in Donetsk Oblast, has been stalling since Vivaldi began. Unable to take those cities, Russia keeps hitting them from the air. On 8 October, a Russian bomb killed 30 people on two buses in Kramatorsk.

Across the Siverskyi Donets

Russian milbloggers said Ukrainian forces liberated Ozerne and advanced east of Pyskunivka toward Kryva Luka, ISW reported. They also acknowledged that Ukrainian troops drove Russian forces out of Pyskunivka. Ukrainians are now counterattacking toward Kryva Luka from the west and northwest, from across the river.

ISW called the repeated Russian claims of a river crossing notable, because the Siverskyi Donets is a significant natural obstacle. Kryva Luka is a dominant height just south of the river. From there, Ukraine could launch further counterattacks. Ukrainian forces appear to have pushed Russian troops off both banks in this area, ISW assessed.

The heights Russia wanted

After Vivaldi cleared ground near Lyman in September, Russia shifted its push south toward Mykolaivka and Sloviansk. Russian forces likely see Mykolaivka, just east of Sloviansk, as a primary objective, ISW said. Its heights would favor an offensive on the city. Ukrainian pushes northeast and southeast of the town now deny Russia that terrain.

East of Kramatorsk, milbloggers claimed Ukrainians liberated Malynivka and advanced between Fedorivka Druha and Holubivka. They also reported gains into southern Minkivka and near Fedorivka. The lines remain tangled. Geolocated footage shows Ukrainian forces striking a Russian position in central Tykhonivka after what ISW assesses was a Russian infiltration.

ISW said the counterattacks may point to a broader Ukrainian goal: pushing Russian forces east, away from the Sloviansk–Kramatorsk area and toward the Siverskyi Donets–Donbas Canal.

The Vivaldi playbook

The counterattacks have run for weeks. On 29 September, Ukrainian military observer Kostiantyn Mashovets reported them in the same areas, saying Russia's 3rd Combined Arms Army had failed to make significant gains. ISW assesses that the attacks build on months of shaping meant to wear down Russia's offensive capacity.

Before Vivaldi, Ukrainian forces targeted Russian drone operators, gaining drone superiority before the counteroffensive. They used the same approach ahead of their Oleksandrivka counterattacks in early 2026.

Moscow appears to see the pattern. A Ukrainian military official said on 7 October that Russia is moving drone units and Spetsnaz from quieter sectors to the Sloviansk–Kramatorsk direction. Ukraine also reorganized its command in and around Donetsk Oblast in early September, which may be blunting Russian attacks from the east, ISW said.

"Distant" and "doomed"

One Russian milblogger called an advance toward the Sloviansk–Kramatorsk area a "distant" prospect, ISW reported. A Russian offensive from Siversk toward Sloviansk may be "doomed" to failure or heavy losses unless Russia retakes the forests south of Lyman, he said.

The counterattacks east of the two cities appear to support Vivaldi, ISW assessed. Together with Russia's defeat north of the river, they could disrupt Russia's offensive toward Sloviansk from the east entirely.

If Ukraine holds Kryva Luka and keeps Russia off the Mykolaivka heights, Moscow's pincer on Sloviansk and Kramatorsk loses the ground it was built on.
