Vladimir Putin told a news conference that he agreed with the idea of a ceasefire, but he immediately spelled out tough conditions that appeared to rule out agreement.

Since the beginning of Russia’s full-scale invasion of Ukraine in February 2022, Russia has attacked the United States and Europe on a near-daily basis using what are often referred to as “hybrid” operations, meant to hide the hand of the Russian government and to remain below the threshold of war so as not to trigger a response.

President Volodymyr Zelenskyy of Ukraine gave no indication Friday that his country’s soldiers would withdraw from Kursk, let alone surrender.
