At least 37 people have been killed following a Russian strike close to the Ukrainian capital of Kyiv in one of the deadliest attacks to hit Ukraine this year, officials have said.The attack sparked a fire in the Bucha district, west of Kyiv, that swept through homes and damaged at least 50 residential buildings, Tymur Tkachenko, head of the local regional military administration, said. In a statement on the attack, Ukrainian president Volodymyr Zelensky said a warehouse had been struck in the village of Myla “followed by a detonation.”He did not give details on the site, but wrote in the same message that Ukrainian law forbade the storage of ammunition close to civilian homes and that criminal proceedings had been opened.“Those who allowed this to happen must be held accountable for their decisions,” Zelensky said. The Ukrainian leader also wrote that a care home for elderly people and people with disabilities had been damaged and that an evacuation from the area was ongoing.Smoke rises in the city during a Russian drone strike, amid Russia's attack on Kyiv (Reuters)Ukrainian prime minister Serhii Koretskyi also didn't offer information on the warehouse targeted, but referenced an attack on the Kyiv suburb of Vyshneve early in July, which hit an ammunition depot, killing 22 and triggering large detonations and fires that tore through nearby homes.“Unfortunately, we can already see that the terrible tragedy in Vyshneve did not become a lesson,” Koretskyi said. “In the fifth year of a full-scale invasion, making the same mistakes is criminal negligence. And all those guilty, without exception, must be severely punished so that such situations do not happen again.”In a statement, Russia's ministry of defense said it had hit a warehouse in Myla storing components and launch boosters for long-range drones. It also said that it had attacked the ports of Mykolaiv and Izmail, as well as a logistics center and warehouse facilities storing parts for Ukraine's Flamingo cruise missiles in the Kyiv region.Zelensky later announced that two officials from state-owned companies, including Ukraine’s largest arms producer, Ukroboronprom, had illegally allowed the storage of weapons on the site in Vyshneve and would be held accountable.Three days of almost constant Russian air raids on Kyiv have choked the economy in the Ukrainian capital and severely disrupted civilian life more than four-and-a-half years after Russia’s full-scale invasion of its neighbour.Officials said the Russian drone strike on a Kyiv-area warehouse sparked a detonation (Reuters)Russian strikes on the southern Kherson region Saturday killed two people and wounded 27 more, Oleksandr Prokudin, head of the region administration, said in a statement on social media.He said that attacks had damaged homes and apartment blocks, and that one child was among the injured. Earlier in the week, Prokudin said that Russia has intensified attacks on critical infrastructure in the region, which is about 70 per cent under Russian control.He also urged tens of thousands of residents to move to safer regions because of the possibility of prolonged power and heating outages this winter.Russia has significantly increased its use of jet-powered drones and their numbers will keep growing as Moscow sees their effectiveness, said Pavlo Palisa, deputy head of Ukraine’s presidential office, in comments to journalists on Saturday.“Means of attack always outpace means of defense. We will certainly need to adapt. It will take time,” Palisa said.Firefighters work at a site of a Russian drone strike in Kyiv (Reuters)He said interceptor drones currently available to Ukraine, which could theoretically intercept jet-powered drones, are not yet to demonstrate the expected effectiveness, though Ukraine is working on solutions.Meanwhile, Ukraine has stepped up its long-range attacks on Russian military industries and energy facilities in recent months, using locally made drones, aiming to cut Moscow’s revenue for its invasion and make Russians feel the consequences.In his evening statement to the nation Friday, Zelensky said Kyiv hoped to increase its long-range strikes on Russia to reach 1000 drone launches every day.“Right now, we average over 300 of our long-range sanctions,” Zelensky said, his preferred term for Kyiv’s long-range attacks that have also lately targeted Russian large-scale online retailers.“There must be more. We have a very specific goal, and we will achieve it.”Moscow’s forces destroyed 313 Ukrainian drones overnight, Russia’s ministry of defense said on Saturday.Ukrainian drone attacks wounded 11 people in Russia’s Rostov region, Gov. Yuri Slyusar said. Writing on social media, he said that nine people were hospitalised, including four children.
