Russia and Ukraine have exchanged another wave of deadly strikes, with attacks reported across several regions of both countries. Russian attacks on Ukraine killed at least four people, according to Ukrainian officials. Two people were killed in the Donetsk region, while another two were killed in the Sumy region. Several other people were injured in different attacks. In the city of Sloviansk in Donetsk, Russian strikes caused fires at a local market. Ukraine's State Emergency Service said that 54 trading pavilions were set on fire. Emergency workers were sent to the area to control the fires and help people affected by the attack. Another Russian attack hit Kramatorsk in the Donetsk region, where people were also killed. The attacks caused damage to buildings and other civilian infrastructure. The northeastern Sumy region was also targeted by Russian drones. Regional officials said a man and a woman were killed in an overnight attack. The Black Sea port city of Odesa was also hit. Local officials said a civilian vessel was damaged and four people were injured. Russia has increasingly targeted Ukrainian ports and coastal areas, which are important for the country's trade and exports. At the same time, Ukraine has increased its long-range drone attacks against targets inside Russia. Russian officials said Ukrainian attacks killed nine people during the latest wave of strikes. Eight people were reportedly killed in the western Belgorod region, which borders Ukraine. Another woman was killed in the southern Astrakhan region. In Belgorod, an attack damaged a car and caused a building to catch fire in the village of Koloskovo. Officials said a child was among those injured and was taken to hospital for treatment. In the Astrakhan region, officials said a Ukrainian drone hit a house and killed a woman. The regional governor said the attack was aimed at an industrial facility, although the facility itself was not damaged. The latest attacks came only one night after Russia described a major Ukrainian drone attack as the largest-scale attack by Ukraine this year. Russian officials said at least seven people were killed during that attack. Ukraine reportedly launched hundreds of drones toward Russia during the weekend. Russian officials said around 822 drones were fired, with hundreds reportedly heading toward the Moscow area. Moscow's regional governor described the attack as one of the largest drone attacks seen in the area in recent memory. Several people were killed in different Russian regions during those attacks. A civilian bus was also hit in Belgorod, according to officials. A warehouse belonging to Wildberries, one of Russia's biggest online retailers, was also damaged. Ukraine has repeatedly targeted Wildberries facilities in recent weeks. Ukrainian officials claim that some Russian military equipment and components are transported through civilian logistics networks. Ukraine's intelligence service has defended the attacks, saying the facilities are part of Russia's wider supply system for the war. Ukraine's intelligence officials have also said that long-range attacks inside Russia will continue. They argue that these attacks are intended to put pressure on Russia and weaken its ability to supply its military. However, both Russia and Ukraine deny deliberately targeting civilians. Ukrainian officials say civilian deaths in Russia can sometimes happen because of falling debris or air-defense systems attempting to destroy incoming drones and missiles. Russia makes similar claims about civilian damage caused by Ukrainian attacks. Russia has also increased its attacks across Ukraine in recent weeks. Ukraine's state energy company Naftogaz said Russian forces attacked its facilities 13 times during the past week. Ukrainian President Volodymyr Zelensky said Russia launched more than 1,550 attack drones, almost 1,560 guided aerial bombs and 62 missiles against Ukraine during the previous week. The attacks affected 13 Ukrainian regions. Russian officials say some of their strikes were aimed at Ukrainian military-related facilities. Russia claimed that attacks around Kyiv targeted a facility producing parts for Ukrainian missiles and a factory making drone components. The continuing attacks show that the war remains highly dangerous for civilians on both sides. Russia launched its full-scale invasion of Ukraine in February 2022 and still controls around one-fifth of Ukrainian territory. Despite international efforts to end the conflict, both countries continue to use drones and missiles against military, industrial and infrastructure targets. The increasing use of long-range drones has also expanded the fighting far beyond the immediate front lines. As the war continues, civilian areas, markets, ports, homes and businesses remain at risk. The latest strikes have once again highlighted the growing danger faced by people living in both Russia and Ukraine.
