[1/3] A destroyed tank is seen in a field in the aftermath of fighting between the Ethiopian National Defence Force (ENDF) and the Tigray People's Liberation Front (TPLF) forces in Kasagita town, in Afar region, Ethiopia, February 25, 2022.
Earlier on Wednesday, the AU had invited media to what it described as a briefing by Obasanjo.
It was only when the event began, about three hours behind schedule, that it became clear a truce was about to be signed.
Implementation of the peace agreement signed today is critical for its success," said Obasanjo, adding that this would be supervised and monitored by a high-level AU panel.
Neither Eritrea nor the regional forces participated in the talks in South Africa and there was no mention at Wednesday's ceremony of whether they would abide by the truce.
