Ethiopia"s Tigray rebels have said they are ready for a ceasefire and will accept a peace process led by the African Union, removing an obstacle to negotiations with the government to end almost two years of brutal warfare, the AFP news agency reported. The Tigray People"s Liberation Front (TPLF) made the announcement amid a flurry of international diplomacy after fighting flared last month for the first time in several months in northern Ethiopia, torpedoing a humanitarian truce. "The government of Tigray is prepared to participate in a robust peace process under the auspices of the African Union," said a statement by the Tigrayan authorities. "Furthermore, we are ready to abide by an immediate and mutually agreed cessation of hostilities in order to create a conducive atmosphere." The Ethiopian government has previously said it was ready for unconditional talks "anytime, anywhere," brokered by the Addis Ababa-headquartered AU. The TPLF had until now vehemently opposed the role of the AU"s Horn of Africa envoy Olusegun Obasanjo, protesting his "proximity" to Ethiopian Prime Minister Abiy Ahmed.AU Commission chief Moussa Faki Mahamat issued a statement welcoming the development as a "unique opportunity towards the restoration of peace" and urged "both parties to urgently work towards an immediate ceasefire, engage in direct talks". UN Secretary-General Antonio Guterres called in a statement for "the parties to seize this opportunity for peace and to take steps to end the violence definitively and opt for dialogue." He said the United Nations is ready to support the AU-led peace process. Taye Dendea, Ethiopia"s state minister for peace, described the TPLF announcement as a "nice development" on Twitter but insisted the "so-called TDF (Tigray Defence Forces) must be disarmed before peace talks start. Clear stand!" The TPLF statement, which coincided with Ethiopia"s new year, made no mention of preconditions, although it said the Tigrayans expected a "credible" peace process with "mutually acceptable" mediators as well as international observers. TPLF leader Debretsion Gebremichael earlier this month proposed a conditional truce calling for "unfettered humanitarian access" and the restoration of essential services in Tigray, which is suffering food shortages and a lack of electricity, communications and banking. In a letter to Guterres, he also called for the withdrawal of Eritrean forces from across Ethiopia, and for troops to pull out of western Tigray, a disputed region claimed by both Tigrayans and Amharas, the country"s second-largest ethnic group. Sunday"s statement said a negotiating team including TPLF spokesman Getachew Reda and General Tsadkan Gebretensae, a former Ethiopian army chief now in Tigray"s central military command, was "ready to be deployed without delay". Debretsion had disclosed last month that two rounds of confidential face-to-face meetings had taken place between top civilian and military officials, the first acknowledgement by either warring side of direct contacts. The AU"s Faki had held talks Saturday with both Obasanjo, the former Nigerian president, and visiting US envoy for the Horn of Africa, Mike Hammer. "May the parties in the conflict have the courage to choose talks over fighting, and participate in an African Union-led process that produces a lasting peace," Hammer said in a new year"s message for Ethiopians on Sunday. Fighting has raged on several fronts in northern Ethiopia since hostilities resumed on August 24, with both sides accusing the other of firing first and breaking a March truce. The latest combat first broke out around Tigray"s southeastern border but has since spread to areas west and north of the initial clashes, the TPLF accusing Ethiopian and Eritrean forces of having launched a massive joint offensive on Tigray on September 1. The United Nations said on Thursday that the renewed fighting had forced a halt to desperately needed aid deliveries to Tigray, both by road and air. — Agencies
