A senior Kremlin official announced Wednesday that U.S. special envoy Steve Witkoff will visit Moscow next week. This visit comes as discussions to resolve the nearly four-year conflict between Russia and Ukraine gain momentum. However, Yuri Ushakov, an adviser on foreign affairs to Russian President Vladimir Putin, stated that Kremlin officials have yet to see a U.S. peace proposal. This follows recent talks involving representatives from the United States, Russia, and Ukraine in Abu Dhabi earlier this week. "Contact is ongoing, including via telephone, but no one has yet sat down at a round table and discussed this point-by-point. That hasn’t happened," Ushakov told Russian state media. Ukrainian officials have not confirmed whether U.S. Army Secretary Dan Driscoll will visit Kyiv in the coming days, as suggested by Trump on Tuesday. Trump’s plan for ending the war was made public last week, prompting a flurry of diplomatic activity. The initial proposal appeared to favor Russian demands for an end to its invasion of Ukraine. Following discussions in Geneva over the weekend between U.S. and Ukrainian officials, Ukrainian President Volodymyr Zelenskyy remarked that the plan could be "workable," although several key issues remain unresolved. A Ukrainian official indicated that Zelenskyy hopes to meet with Trump soon. Witkoff's involvement in the peace efforts gained attention on Tuesday when reports surfaced that he had advised Ushakov on how to present the peace plan to Trump. Trump characterized Witkoff’s approach as "standard" negotiating practice. "He’s got to sell this to Ukraine. He’s got to sell Ukraine to Russia," Trump said while aboard Air Force One, en route to Florida. "That’s what a dealmaker does." As diplomatic efforts unfold, the ongoing conflict continues to escalate. The southern Ukrainian city of Zaporizhzhia experienced a significant Russian drone attack overnight, damaging over 50 residential buildings, including a university dormitory. Ivan Fedorov, head of the regional military administration, reported that at least 19 people were injured in the attack. In response, Russian air defenses intercepted 33 Ukrainian drones overnight across various regions, including the Black Sea, according to the Russian Defense Ministry. European nations, concerned about Russia's aggression and their own security, are striving to make their voices heard in the negotiations led by the United States. German Chancellor Friedrich Merz emphasized the need for a swift resolution to the conflict. "But an agreement negotiated by great powers without the approval of the Ukrainians and without the approval of the Europeans won’t be a basis for a real, sustainable peace in Ukraine," he stated to lawmakers in Berlin. "Europe is not a plaything but a sovereign actor for its own interests and values." Ursula Von der Leyen, head of the European Union’s executive, expressed optimism about recent developments, stating there is "an opportunity here to make real progress" toward peace. She stressed that any settlement must include future security guarantees for Ukraine and should not impose limitations on its armed forces or hinder its path to NATO membership. "As a sovereign nation, there can be no limitations on Ukraine’s armed forces that would leave the country vulnerable to future attacks," she said during a speech at the European Parliament in Strasbourg, France. "This is as much about deterrence as it is about Europe’s security, because Ukraine’s security is Europe’s security."
