The European Union has adopted new sanctions listings targeting individuals involved in Russia's military-industrial complex, EU foreign policy chief Kaja Kallas said on Friday on social media platform X. She added this was in response to the recent Russian airstrikes against Ukraine but did not specify which individuals were sanctioned. United Nations chief Antonio Guterres on Thursday condemned both sides for attacks on civilian areas as Ukraine and Russia kept up their artillery war. Ukraine struck two Russian oil refineries hundreds of kilometers from the border in an overnight attack, President Volodymyr Zelensky said Thursday, as Russia hit a train station and commercial ship in Ukraine. Both sides have been intensifying their long-range attacks in recent months, leading to a jump in civilian deaths. Kyiv has been firing record numbers of drones at Russia, while Moscow has been launching all-time high missile attacks. Zelensky said Ukraine had hit oil refineries in the Bashkortostan and Yaroslavl regions -- about 1,300 (800 miles) and 700 kilometers from the front. Russian missile attacks on Kyiv a day earlier had killed at least 17 and destroyed warehouses belonging to a number of retailers in what was widely seen as a direct response to Ukraine's campaign targeting Wildberries, widely dubbed "Russia's Amazon.” But Guterres called Thursday for an end to the deadly attacks on civilian areas in both countries. "These latest series of attacks follow an alarming pattern of escalating strikes against populated areas," spokesman Farhan Haq told reporters. "Attacks against civilians and civilian infrastructure are a clear violation of international humanitarian law, and must stop immediately," he added.
