An exchange of more than 800 prisoners linked to Yemen’s long-running war began on Friday, the International Committee for the Red Cross said. The United Nations-brokered deal, in the works for months, comes amid concerted diplomatic efforts to negotiate an end to the conflict.

The three-day operation will be the most significant prisoner exchange in Yemen since the Saudi-led coalition and their rivals, the Iranian-backed Houthi rebels, released more than 1,000 detainees in October 2020.

Thousands of people are still believed to be held as prisoners of war since the conflict erupted, with others missing. But Fabrizio Carboni, the Red Cross’ regional director, said the release “gives a sense of momentum” for efforts to end the war.
