The internationally recognized Yemeni government and the Iran-aligned Houthi group are set to exchange more than 1,600 prisoners and detainees under a UN-backed agreement, described by the United Nations as the largest release since the start of Yemen’s conflict. The swap takes place after years of fighting that began when the Houthis seized Sanaa in 2014 and was followed by a Saudi-led military intervention supporting the government in 2015.

The United Nations special envoy’s office for Yemen says the exchange will involve detainees held by both sides, with releases coordinated through international mechanisms. Al Jazeera reports that the exchange is facilitated by the International Committee of the Red Cross (ICRC), which typically supports detention monitoring and prisoner exchanges in conflict settings.

Both outlets characterize the deal as a major confidence-building step amid continued hostilities, but they provide no additional details in the cited reports on the timeline beyond the announcement, the exact numbers by side, or whether specific high-profile detainees are included.
