President Biden on Wednesday denounced Russia’s large-scale Christmas Day attacks on Ukraine that damaged critical energy infrastructure and vowed to continue a U.S. surge in weapons deliveries to Kyiv.

The big picture: Ukrainian President Volodymyr Zelensky on X called the attacks “inhumane,” while Russia’s Defense Ministry said the “long-range precision weapons and strike drones on critical energy infrastructure facilities” in Ukraine had achieved the goal of Russian leader Vladimir Putin’s forces.
