Talks between the Ethiopian government and the rebel authorities in Tigray aimed at finding a peaceful resolution to their devastating two-year conflict were continuing Monday, a diplomat said. The negotiations led by the African Union began last Tuesday in South Africa, the first formal dialogue to try to end a war that has killed many thousands of people and unleashed a desperate humanitarian crisis in northern Ethiopia. South Africa had initially said the talks being held in Pretoria would run until Sunday, but they remain shrouded in secrecy. Ebba Kalondo, spokeswoman for AU Commission chair Moussa Faki Mahamat, said in a message to AFP that “there was no date limitation put on the talks”. A diplomat with knowledge of the discussions confirmed to AFP that the talks were continuing on Monday, without giving further details, adding: “They are very strict about confidentiality.” A source close to the Tigrayan delegation in South Africa had told AFP at the weekend that the talks would likely continue until Tuesday. Since the negotiations began, intense fighting has continued unabated in Tigray, where government troops backed by the Eritrean army and regional forces have been waging artillery bombardments and air strikes, capturing a string of towns from the rebels. Diplomatic efforts to try to bring the government and the rebels to the negotiating table gathered pace after combat resumed in late August, torpedoing a five-month truce that had allowed limited amounts of aid into Tigray. The international community has voiced deep alarm over the ongoing fighting and the human cost it has exacted on civilians caught in the crossfire. It is calling for an immediate cessation of hostilities, humanitarian access to Tigray where many face hunger, and a withdrawal of Eritrean forces, whose return to the battleground has raised fears of renewed atrocities against civilians.
