MOSCPW (AP) – Ukrainian drones struck two sprawling warehouses, one of them just east of Moscow, as part of attacks overnight and on Saturday afternoon that killed nine people and wounded more than 80, Russian officials said.

Kyiv’s forces have pressed their relentless aerial campaign against energy infrastructure and military targets inside Russia, aiming to undermine Moscow’s war effort and make Russians feel the consequences of the Kremlin’s all-out invasion of Ukraine that is well into its fifth year.

Two sprawling warehouses of Russia’s major online retailer, Wildberries, were hit by Ukrainian drones overnight, according to Russian officials — one in the town of Kotovsk in the Tambov region, some 360 kilometers (220 miles) from the border with Ukraine, and another in the city of Elektrostal, about 50 kilometers (30 miles) east of Moscow.

A Ukrainian drone also hit an oil depot in the city of Noginsk, just north of Elektrostal, sparking a fire and prompting evacuations of a nearby maternity hospital and a residential building, according to the governor of the Moscow region, Andrei Vorobyov. Drone debris also hit a kindergarten building, Vorobyov said, sparking a fire that has since been put out.

Seven night shift workers were killed at the warehouse in Kotovsk and 25 others were wounded, Tambov regional Gov. Yevgeny Pervyshov said.

A total of 61 people were wounded in the Moscow region, Vorobyov said: 20 sought outpatient care, while 40 others were hospitalized. One person died of their injuries, he said.

One more person was killed and another wounded in a Ukrainian drone attack on Russia’s Belgorod region on Saturday afternoon, according to local authorities.

Both warehouses caught fire, Wildberries founder Tatyana Kim said, and the blaze in Kotovsk was put out. Images and footage released by Russian online outlets showed a fire raging at the Elektrostal facility, with massive plumes of smoke towering over it.

Ukrainian President Volodymyr Zelenskyy said in a Telegram post on Saturday that Ukrainian long-range strikes hit two “significant logistical facilities in the Moscow and Tambov regions.”

“These facilities were used by the aggressor to supply sanctioned components for the production of drones and navigation equipment,” he wrote. An oil facility was also hit, he said.

In the city of Vladimir, some 180 kilometers (110 miles) east of Moscow, a Ukrainian drone hit a residential building, sparking a brief fire, Vladimir Gov. Alexander Avdeyev said. There were no casualties, he added.

Ukrainian special operations also conducted strikes against targets in the Sea of Azov and in occupied territory, Zelenskyy said.

Ukraine’s General Staff said in a statement on Saturday that the fuel depot in Noginsk that was targeted overnight supplied the Russian armed forces. It also reported hitting two tankers, two floating cranes and a tugboat in the Black and Azov seas, saying the vessels were used to transport oil, fuel and military cargo.

Separately, the military said it struck a Project 10410 Svetlyak-class patrol ship in Kerch, describing it as the second vessel of that class hit in two days, as well as a railway bridge over the Bila River near Sabivka in the occupied Luhansk region that it said Russia uses for military logistics.

Overall, the Russian Defense Ministry said its air defenses overnight intercepted 379 Ukrainian drones over 19 Russian regions, as well as the illegally annexed Crimea, the Sea of Azov and the Black Sea.
