Russian air strikes on several regions across Ukraine damaged critical civilian infrastructure, as a Ukrainian drone attack halted operations at a major oil-pumping station deep inside Russia.
Ukrainian air defense reported shooting down or neutralizing 97 of 115 drones launched by Russia overnight. A "massive attack" by Russian forces struck critical infrastructure and a residential building in Ukraine's west-central Vinnytsia region, local officials said.
Railway service in Vinnystia was disrupted, but no casualties were reported, regional official Natalia Zabolotna said on Telegram.
Russian drone strikes also damaged two residential high-rises as well as other structures in Zaporizhzhya, regional military administration chief Ivan Fedorov said. One person was killed and two more wounded in a missile strike on the Sumy region.
Both the Zaporizhzhya and Sumy regions, which are partly occupied by the Russian forces, have come under frequent attack recently.
In the southern city of Kherson, near Russian-occupied territory across the Dnieper River, Russian shelling damaged a private home and commercial buildings.
Meanwhile, the governor of Russia's Chuvashia region, Oleg Nikolayev, said Ukrainian drones struck an oil-pumping station near the village of Konar, which is about 1,200 kilometers from Ukraine. Operations were halted and the strike caused minor damage and no casualties, he said on Telegram.
Ukraine's Security Service later confirmed that its long-range drones had been used in the attack, claiming that they had caused a fire at the facility.
The strikes come at a time when prospects for peace seem as distant as ever and Russia's full-scale invasion nears to continue into its fourth winter.
After returning from his trip to the United States, Ukrainian President Volodymyr Zelenskyy said Kyiv would not hesitate to respond to Russian attacks if further strikes cause energy outages in Ukraine.
"If [Russia] threatens a blackout in the Ukrainian capital, the Kremlin should know -- there will be a blackout in Russian capital too," Zelenskyy told journalists on September 27.
In recent months, Ukraine has stepped up attacks targeting refineries, export terminals, and other oil infrastructure, seeking to undermine Russia's capacity to fight the war by reducing its export revenues and cause domestic discontent by creating shortages and pushing up prices.
A US effort to broker a peace deal has brought little progress. The positions of Ukraine and Russia remain far apart, and US President Donald Trump has so far not succeeded in organizing a trilateral summit or a face-to-face meeting between Russian and Ukrainian presidents.
