An Ethiopian Airlines plane has landed in Somalia's capital Mogadishu — the first such flight in four decades.
All flights were halted in the 1970s after a border conflict broke out between the two countries.
The political landscape in the Horn of Africa region has changed dramatically since April, when Ethiopian Prime Minister Abiy Ahmed came to power.
He is currently holding a meeting in the Ethiopian city of Gondar with the Somali president, Mohamed Abdulahi Farmajo and the Eritrean president, Isias Afeworki.
The former rivals are looking at ways to boost trade between their countries.
