The two sides in Yemen's conflict agreed to free 887 detainees and to meet again in May after 10 days of negotiations in Switzerland, the United Nations and the International Committee of the Red Cross said on Monday.
The deal which comes ahead of Ramadan adds to optimism for further releases and a final resolution to the conflict following the resumption of ties between Iran and Saudi Arabia this month.
"It's an expression of hope. It's an expression of humanity and it indicates the way ahead for all parties to the conflict," said Fabrizio Carboni, ICRC regional director for the Middle East, who was seated between the two delegations.
