Yemen's legitimate government and the Iran-backed Houthi militants agreed Thursday to free more than 1,600 detainees in the largest swap during Yemen's 11-year war.
The deal was signed in Amman, Jordan, after 14 weeks of negotiations observed by UN officials and the International Committee of the Red Cross. The swap built on previous understandings that started from Muscat in late 2025 and included indirect negotiations rounds in Riyadh, before culminating in an agreement in Jordan.
UN Secretary-General António Guterres welcomed the deal and called on the parties to move swiftly toward implementing it so families could soon be reunited, a UN spokesperson said.
UN Special Envoy for Yemen Hans Grundberg said the deal covered the largest release of “conflict-related detainees.” An ICRC in a statement said both sides agreed on the identities of the detainees to be released, and added that the Geneva-based organization is ready to facilitate their repatriation.
The head of the government delegation, Yahya Kazman, said in a post on X that a “number of politicians and media professionals" held by the Houthis will also be released. He did not give details.
It was not immediately clear when the release would start.
Guterres also called on the government and the Houthis to build on the positive momentum generated by the deal and to engage constructively toward an inclusive political process for a just and lasting peace in Yemen, Guterres’ deputy spokesperson Farhan Haq said.
“The Secretary-General further urges the Houthis to immediately and unconditionally release all arbitrarily detained personnel from the United Nations, NGOs, civil society and diplomatic missions,” Haq said.
Sustained diplomacy
“These negotiations have been extraordinarily complex,” Grundberg told reporters. “They required persistence, flexibility, and willingness by all sides.”
He said the agreement demonstrated that sustained diplomacy could still produce results despite years of conflict and mistrust.
“This outcome is a clear demonstration of what sustained and determined negotiations can produce,” he added. “It proves that when the parties choose to engage in dialogue, they can deliver on the priorities that weigh most heavily on Yemeni families and build confidence for the wider peace process.”
Grundberg also renewed calls for the release of UN personnel and others arbitrarily detained in Yemen.
“I hope that today’s momentum can help advance the release of UN and other colleagues who remain in arbitrary detention,” he said.
Some 1,100 of the almost 1,700 detainees are Houthi-affiliated, while seven Saudis and 20 Sudanese are among the 580 detainees that will be released by the other side.
'Major breakthrough'
The government delegation said the deal calls for the release of 1,750 detainees, including 27 members of the Arab Coalition forces. It said the development was a “real changing point in this complex humanitarian file.”
A government statement said the negotiations faced major hurdles and complications but a “national and humanitarian approach” ensured their success.
It hailed the role played by Saudi Arabia, Jordan and the ICRC in the file.
The swap agreement includes mutual prisoner and detention center visits after the exchange is complete in what was seen as an efforts to build trust between the two the government and Houthis.
In Houthi-held Sanaa, head of the Houthis’ Supreme Political Council Mahdi al-Mashat welcomed the agreement, saying the militants have offered “all facilitations” to ensure its success, reported Houthi media.
He claimed that the prisoner file had always been a top priority for the Houthis, vowing to pursue the release of remaining detainees by all possible means.
Observers said the swap was a new test for the Yemeni parties to translate humanitarian understandings into tangible steps on the ground, given the failure of previous swaps due to various differences.
International mediators are hoping the implementation of the latest swap will generate a positive conditions that would push forward the stalled political process.
