Ukrainian President Volodymyr Zelensky has appealed to global leaders to stop Russia from driving a new arms race, warning that the combination of autonomous drones and artificial intelligence poses new risks to humanity. Zelensky made the warning during an address Wednesday to the U.N. General Assembly, where he said Russia will expand its aggression beyond Ukraine if it’s not stopped. Separately, Zelensky told Axios he does not seek to lead Ukraine once conflict with Russia has ended, saying he intends to organize elections if a ceasefire is reached.

On Wednesday, a Kremlin spokesperson lashed out over President Trump’s claim that Ukraine could claw back territory captured by Russia’s full-scale invasion, saying Russia has “no alternative” but to continue its war in Ukraine.
