Russia's Defense Ministry claims its forces have taken control of the entire Luhansk region in Ukraine. However, a Ukrainian military official denies this, stating that small areas are still held by Ukrainian forces. Russia has previously made false claims of advances. Meanwhile, Ukrainian President Volodymyr Zelenskyy is preparing for talks with U.S. envoys trying to mediate an end to the conflict. A Russian drone strike killed four people in Ukraine's Cherkasy region on Wednesday. Ukraine's air force says it downed 298 drones in overnight attacks.

President Donald Trump says it's possible that Ukraine can defeat Russia, but he's doubtful that it will happen. The latest comments from Trump added a fresh layer of skepticism toward Kyiv as he plans to meet again with Russian President Vladimir Putin to discuss ending the war. Trump on Monday said Ukrainians "could still win it" but added, "I don't think they will." Trump last month reversed his long-held position that Ukraine would have to concede land and said it could win back all the territory it has lost to Russia. But he changed his position again last week after holding a call with Putin and meeting with Ukrainian President Volodymyr Zelenskyy.
