Putin suggests Russia won't accept Trump's plan for unconditional ceasefire

He noted that his troops had been retaking occupied territory in Russia's Kursk region in recent days and advancing along the front lines in Ukraine, and asked, "What would happen during those 30 days?"

• Specifically, Putin raised the fate of the Ukrainian soldiers still in Kursk, asking, "Would it mean that everybody there would leave? Should we release them after they committed serious crimes against civilians?"
• But Putin also thanked President Trump for his efforts and took a less hardline position than his senior aide, Yuri Ushakov, who said earlier on Thursday that Trump's proposal was "nothing other than a temporary timeout for Ukrainian soldiers."
• "The idea is good and we absolutely support it, but there are issues we need to discuss, and I think we need to negotiate with our American colleagues," Putin said.

The latest: Trump called Putin's response "promising but incomplete" at the top of his meeting with NATO Secretary General Marc Rutte.

• He added that he is willing to discuss the ceasefire proposal directly with Putin.

What's next: White House envoy Steve Witkoff arrived in Moscow on Thursday to meet with Putin about the ceasefire proposal.

• Ushakov said Putin and Witkoff would meet privately on Thursday night.
