Russia and Ukraine have launched another major wave of attacks as the war between the two countries continues to intensify. Russia's Defence Ministry said Ukraine carried out what it described as the largest-scale drone attack of 2026. Russian officials said 822 Ukrainian drones were shot down or intercepted overnight across different parts of the country. Moscow Mayor Sergei Sobyanin said more than 600 drones were intercepted while heading toward the Russian capital. The large number of drones caused fires and damage in several areas around Moscow. One of the most notable targets was a large warehouse belonging to Wildberries, one of Russia's biggest online shopping companies. A fire broke out at the facility in the Moscow region following the reported Ukrainian drone strike. Ukraine said the warehouse was an important logistics centre and claimed the facility had been disabled. Ukrainian officials said it was the largest Wildberries warehouse by area, covering about 250,000 square metres. Ukraine also claimed that seven of the company's 10 largest logistics centres have now been disabled in recent weeks. Ukraine has accused Wildberries facilities of helping Russia's military by providing equipment and other supplies. Russia denies the accusation and says the company is a civilian online retailer. At the same time, Russia launched a large number of missile and drone attacks against Ukraine. Ukrainian officials said at least eight people were killed and 39 injured in the latest attacks across the country. Several regions were affected, including Kyiv, Sumy, Donetsk, Kherson, Zaporizhzhia, Dnipropetrovsk and Odesa. In Kyiv, a major book and second-hand market in the Pochayna area was badly damaged by a Russian strike. Hundreds of market stalls were destroyed, leaving books, records, toys, posters and other goods scattered among the rubble. Firefighters continued working at the market to put out fires. Thick smoke and flames could be seen rising from the damaged buildings. Business owners said they had lost large amounts of stock and money. One market owner told the BBC that her business was very important to her and that she had lost about 500,000 Ukrainian hryvnias worth of goods. Other traders said they had lost things that they had spent many years building up. The destruction has also affected Ukrainian publishing companies that used the market and nearby warehouses. One publisher estimated that his company alone could lose millions of hryvnias because of the damage. Russia said it had targeted locations connected to Ukraine's military. However, the Kyiv market was mainly known for selling books and second-hand goods. Other parts of Ukraine were also hit. In the Odesa region, officials reported several injuries after residential buildings and a post office were struck. Emergency workers continued dealing with the damage. In Russia, Ukrainian attacks also caused deaths. Officials in the Rostov region said five people were killed, while another woman was reportedly killed in the Belgorod region after a bus was struck. An elderly person was also reported killed in a drone attack in the Moscow region. The attacks also affected neighbouring Romania. Romania said a drone entered its airspace and was shot down by a Spanish F-18 fighter jet operating as part of a NATO air-policing mission. Romanian officials said the drone entered from the direction of Moldova. NATO said the drone appeared to be Russian, although the incident remained under investigation. Ukrainian President Volodymyr Zelensky has called for more air-defence systems from European countries. He said stronger air defences are urgently needed to protect Ukrainian cities and civilians from Russian missile and drone attacks. The latest strikes show that the war is continuing to spread beyond the main battlefield. Ukraine is increasingly attacking targets inside Russia, while Russia continues to launch large-scale attacks against Ukrainian cities and infrastructure. With both sides using large numbers of drones and missiles, civilians on both sides are facing increasing risks, while important businesses, warehouses, markets and infrastructure continue to suffer damage.
