 Russian shelling in Ukraine killed four on Saturday as the two countries exchanged drone attacks, one of which set ablaze a Russian oil depot deep inside the Rostov region. Two people died in Ukraine's partly occupied Kherson region, and two were wounded in the attack close to the regional capital. It came a day after Ukrainian President Volodymyr Zelensky addressed U.S. governors at the National Governors Association summer meeting in Salt Lake City, using the national platform to ask for aid to combat Russia's attacks.
