In Ukraine, gunfire echoed over the presidential palace in Kyiv earlier today as Ukrainian air defenses fired on a Russian drone buzzing overhead. The incident came as Ukrainian President Volodymyr Zelensky held talks with visiting U.K. Prime Minister Keir Starmer, who agreed to send further military assistance to Kyiv as he signed a so-called 100-year partnership treaty with Ukraine. Their meeting came a day after Ukraine’s military said it had launched its largest attacks yet on Russian soil, prompting retaliatory threats from Moscow. Since November, Ukraine has increasingly been using U.S.-made ATACMS missiles and British Storm Shadow missiles to strike deep inside Russian territory.

Meanwhile, the Biden administration on Wednesday imposed new sanctions on hundreds of Russian entities and individuals accused of supporting Russia’s invasion of Ukraine. The executive order requires Congress to be notified before any of the sanctions can be lifted — a move that legal experts have called “Trump-proofing.”
