The remarks came after Ukrainian President Volodymyr Zelensky welcomed news of European presence at the next round of the US-brokered peace talks, saying he hoped the agenda would include efforts towards ceasefires and defusing the conflict.

"We are also working toward what would be the largest prisoner exchange of the war, potentially reuniting thousands of people with their families," Kushner wrote on X, without giving details of the deal.
