The United Nations announced on Wednesday that warring factions in Yemen have made progress towards finalizing a long-awaited exchange of prisoners, originally agreed upon six years ago.

Talks facilitated by Oman have brought together the Saudi-backed Yemeni government and the Sanaa government, who control most of the populated areas in Yemen.

"The parties have reached an understanding about arrangements to release conflict-related detainees," the office of UN special envoy Hans Grundberg said.

"The office of the UN special envoy stresses the importance of finalizing this understanding responsibly to achieve tangible results toward releasing conflict-related detainees in accordance with the ‘all for all’ principle," the statement added.

The negotiations are underpinned by the Stockholm agreement of 2018, which aimed to secure the release of prisoners detained during Yemen's decade-long war.

A previous reconciliation effort in early 2023, facilitated by Saudi Arabia and Iran, led to the release of nearly 900 prisoners in April that year.

But recent peace efforts have faced challenges since the start of US-UK aggressions on Yemen. 

Mohamed Qahtan, a prominent official of the Saudi-backed Al-Islah party held by Sanaa since 2015, is among those expected to be released in the upcoming exchange.

Sanaa negotiator Abdelkader al-Murtada confirmed that his leadership has agreed to release Qahtan in exchange for 50 prisoners held by the Saudi-backed government.
