Thousands of prisoners could soon be heading home in what is being described as the largest prisoner exchange of the Russia-Ukraine war. US envoys Steve Witkoff and Jared Kushner announced the breakthrough after a whirlwind day of diplomacy, meeting Vladimir Putin in Moscow first and then Ukrainian President Volodymyr Zelensky near Dublin. Kushner said the US is working toward the biggest swap of the war, one that could reunite thousands of people with their families. Zelensky called it "a real result" and said Russia has agreed, adding that Ukrainian soldiers will return home. The deal was first agreed in principle during US-brokered talks in Abu Dhabi this week.

Still, many details are missing, including the exact number of prisoners, who is on each list and when the swap will happen. Officials have not given a firm date. The humanitarian step also does not mean peace is near, because Putin reportedly held to his hard line on territory and security arrangements even while backing more negotiations. Kushner has acknowledged that "significant differences remain" between the two sides. Both sides also agreed to bring European partners into the next round of talks, and Witkoff said the next meeting is already scheduled.
