CHERNIHIV REGION, Ukraine (AP) — An exchange of prisoners between Russia and Ukraine from their more than three-year war was underway Friday, a senior Ukrainian official said. The swap was not yet finished, according to the official, who spoke on condition of anonymity because he was not authorized to speak publicly.

An exchange of prisoners of war (POWs) between Ukraine and Russia taking place on May 23 is still ongoing, a source familiar with the exchange told the Kyiv Independent, after U.S. President Donald Trump said the swap had been "completed.

The U.S. president says the onus is on Russia and Ukraine, not Washington, to end the war, according to a report.

The large prisoner swap between Ukraine and Russia on May 25 has not yet been completed. The exchange process is ongoing, sources say. US President Donald Trump said on Truth Social that the prisoner exchange between Ukraine and Russia had been completed.

President Donald Trump said on Friday that a major prisoner swap was just completed between Russia and Ukraine.

President Donald Trump announced a "major prisoners swap" had taken place between Russia and Ukraine. The two sides had agreed to exchange 1,000 prisoners each at their direct talks in Istanbul last week, the first time Russia and Ukraine had met for negotiations in more than three years.
