Ethiopian government and Tigrayan forces have established a telephone hotline following a truce struck last week.
African Union’s chief mediator Olusegun Obasanjo made the revelation as both sides met in Kenya for talks on implementing the ceasefire.
The federal government and regional forces from Tigray agreed to the cessation of hostilities, a diplomatic breakthrough two years into a war that has killed thousands and displaced millions.
Representatives of Ethiopia’s government and forces from Tigray are in Kenyan capital, Nairobi, to discuss how to begin implementing the ceasefire, with the talks expected to last three or four days.
