Chatham House observes, "the scale of Eritrean defeat was apparent when Eritrea unexpectedly accepted the OAU peace framework." Having recaptured most of the contested territories – and having learned that the Eritrean government would withdraw from any other territories it occupied at the start of the conflict, in accordance with a request from the OAU – Ethiopia declared the war was over on 25 May 2000. Cessation of hostilities On 18 June 2000, the parties agreed to a comprehensive peace agreement and binding arbitration of their disputes under the Algiers Agreement. On 31 July 2000, the United Nations Security Council adopted Resolution 1312 and a 25-kilometer-wide Temporary Security Zone (TSZ) was established within Eritrea, patrolled by the United Nations Mission in Ethiopia and Eritrea (UNMEE) from over 60 countries. On 12 December 2000 a peace agreement was signed by the two governments. Impact Casualties Eritrea officially claimed that 19,000 Eritrean soldiers were killed during the conflict; Ethiopia claimed to have lost between 34,000–60,000. Meanwhile, Voice of the Democratic Path of Ethiopian Unity, a clandestine political opposition group, alleged that 123,000 Ethiopians were killed, while other reports place the number of Eritrean deaths at around 150,000. Most international reports put the total war casualties from both sides as being around 70,000, but some analysts within the region suggested that the overall death toll may have been as high as 300,000. All these figures have been contested, and other news reports simply state that "tens of thousands" or "as many as 100,000" were killed in the war. War conduct Eritrea accused Ethiopia of using "human waves" to defeat Eritrean trenches. But according to a report by The Independent, there were no "human waves" because Ethiopian troops instead outmanoeuvred and overpowered the Eritrean trenches. Displacement, abuse and torture The fighting led to massive internal displacement in both countries as civilians fled the war zone – by the end of May 2000, Ethiopia occupied about a quarter of Eritrea's territory, displacing 650,000 people, and destroying key components of Eritrea's infrastructure. The Eritrean government forcibly expelled an estimated 70,000 Ethiopians according to the report by Human rights Watch. Ethiopia expelled 77,000 Eritreans and Ethiopians of Eritrean origin it deemed a security risk, thus compounding Eritrea's refugee problem. The majority of those were considered well off by the Ethiopian standard of living. They were deported after their belongings had been confiscated. Ethiopians living in Eritrea were
