Ukrainian drones struck multiple Russian oil facilities, refineries, depots, and tankers on July 9, 2026, one day after a U.S. pledge to license Patriot air defense production in Ukraine. The attacks caused fires at sites in Tver and Vyazniki and set two tankers ablaze in the Sea of Azov, contributing to reported fuel shortages and rationing in Russian regions. All claims draw from The Hindu and New York Post reporting, with one unverified Russian air defense claim noted separately.
