Ukraine war briefing: Kyiv says air raid warning app likely hacked after users receive false alerts

Ukraine's air force suspects its air raid alert app was hacked, displaying false nuclear and chemical alerts. Meanwhile, 167 people were evacuated from Kherson as a temporary ceasefire ended, with concerns about renewed fighting. Ukrainian forces resumed attacks on Russian oil refineries despite pressure from Donald Trump, who linked rising fuel prices to Ukraine's actions. President Zelenskyy stated Ukraine would halt refinery strikes if provided with Patriot missiles, as the U.S. approved their sale, although delivery may take years.
