The death toll from a Russian strike on an arms depot near the Ukrainian capital, Kyiv, has risen to 38, making it the deadliest attack of the war so far this year, President Volodymyr Zelenskyy said.
Emergency workers on Sunday continued to extinguish fires and explosions that began on Saturday in the village of Myla, Zelenskyy said in a post on Telegram. Bomb disposal teams were also working to clear the site.
He said 20 people were injured, while four remained missing.
The attack was the second to hit a munitions depot near Kyiv within two months. Officials voiced anger that arms were still being stored so close to residential areas. Ukrainian prosecutors have opened an investigation into alleged criminal negligence.
Separately, Zelenskyy said in a video message that Kyiv is preparing for a new round of talks with representatives of US President Donald Trump, with further details expected on Monday.
Zelenskyy stressed that Ukraine is "doing everything possible to ensure that war does not remain the only option for future developments", even as Moscow intensifies its strategy of exhaustion.
"Russia's current tactic is to wear down Ukraine, and above all, to wear down Ukrainians," Zelenskyy said, pointing to relentless air strikes across the country.
According to the Ukrainian president, Russian forces launched nearly 1,500 drones over a four-day period, including roughly 800 jet-powered Shahed variants. He described intercepting the faster, jet-powered models as the military's "most difficult task".
To counter the threat, Kyiv is working to secure the necessary interceptor systems. Four firms have already developed suitable interceptor drones, with technology from one company proving particularly effective, Zelenskyy added.
Meanwhile, Russia's Ministry of Defence said its forces were preparing to launch "massive strikes" against Ukraine's energy infrastructure. The announcement followed a Ukrainian drone campaign targeting a major Russian e-commerce platform and the country's oil and gas sector, which Kyiv says both funds and directly fuels Moscow's war effort.
During previous winters, Russian forces systematically struck Ukraine's power grid, depriving thousands of people of heat and electricity in freezing temperatures. Ukrainian officials have repeatedly warned that the coming winter may prove the most challenging since Russia launched its full-scale invasion in February 2022.
The Ukrainian military said it carried out overnight attacks on an oil refinery in Russia's Leningrad region and a military base in the Krasnodar region.
One person was killed in a separate Ukrainian attack on a mine in the Russian-controlled part of the Luhansk region in eastern Ukraine, according to Moscow-installed Governor Leonid Pasechnik.
US-led diplomatic efforts to end the conflict, Europe's deadliest since World War II, have been at a standstill for months. Russia has demanded sweeping territorial and political concessions from Ukraine, which Kyiv has ruled out as tantamount to capitulation.
