The WFP announcement came a day after a medical aid convoy from the International Committee of the Red Cross entered Tigray, the first ICRC trucks to arrive in the region following the deal between the Ethiopian government and the Tigray People's Liberation Front (TPLF).
The agency said the convoy had travelled along a route through neighboring Amhara for the first time since June 2021, when TPLF fighters recaptured Tigray from federal forces and expanded into the bordering regions of Amhara and Afar.
"More food, nutrition, medical cargo will follow imminently, via all routes possible," the WFP said on Twitter.
Tigray, a region of six million people, has been suffering from a severe lack of food and medicine, as well as limited access to basic services including electricity, banking and communications, with the UN warning that many people were on the brink of starvation.
The restoration of aid deliveries to Tigray was a key part of the agreement signed in South Africa to silence the guns in the two-year conflict that has killed untold numbers of people and unleashed a humanitarian crisis in northern Ethiopia.
