Flights carrying patients in need of urgent medical attention began from the Yemeni capital Sanaa on Monday.
The United Nations and World Health Organization will supervise patient transfers and flights which are expected to go to Amman in Jordan and Cairo in Egypt, aid organization the Norwegian Refugee Council (NRC) said.
The medical flights were the result of months of negotiations and the project had received an “extraordinary” amount of diplomatic support, UN Yemen Envoy Martin Griffiths said in an address to the Security Council last month.
The United Nations has been trying to re-launch political negotiations to end the war.
A diplomatic source said around 60 patients and relatives are expected to leave on flights this week and the NRC said seven patients are expected on the first flight.
