A major prisoner exchange between Russia and Ukraine is now under way, according to a Ukrainian source familiar with the matter. The swap started on Friday, with Kyiv and Moscow swapping hundreds of prisoners.

CHERNIHIV REGION, Ukraine (AP) — Russia and Ukraine began a major prisoner exchange Friday, swapping hundreds of soldiers and civilians in the first phase of an exchange that was a moment of cooperation in otherwise failed efforts to reach a ceasefire in the 3-year-old war.

Russia and Ukraine have each handed over 390 soldiers and civilians in the biggest prisoner exchange since the start of the full-scale Russian invasion in 2022. They both returned 270 servicemen and 120 civilians on the Ukrainian border with Belarus, as part of the only deal agreed in direct talks in Istanbul a week ago.
