Relations between Eritrea and Ethiopia have historically been difficult. Eritrea won independence from Ethiopia in 1993 after a 30-year war. A bitter border war between the two countries began a few years later. But by 2020, Eritrea sent troops to fight alongside the Ethiopian government against rebel forces in its northern Tigray region.

Kalkidan Yibeltal is a BBC correspondent in Addis Ababa. He explains the complex history between the two countries, and looks at the tentative peace now emerging in Tigray.
