ASMARA (Reuters) - The Eritrean government appeared on Friday to cautiously accept an international four-point plan to settle a bloody border row with Ethiopia but said serious details remained unresolved. „The four-point recommendations … address the paramount issues that the government of Eritrea has been raising and are therefore not controversial,“ the government said in a statement issued in the Eritrean capital. „At the same time, the government of Eritrea believes that the facilitation process has not been consummated and that there are still serious issues of detail and implementation that need to be worked out in the period ahead,“ it said. The plan — brokered by diplomats from the United States and Rwanda — calls for troops from Ethiopia and Eritrea to withdraw from disputed territory, for an observer force to be deployed, for the return of civilian administration to disputed areas and for an investigation into roots of the conflict. Ethiopian Prime Minister Meles Zenawi told a news conference on Thursday that his government had accepted the plan, but Friday‘s statement was the first by Eritrea on the proposals. Ethiopia and Eritrea have argued peacefully over their border for years, but the dispute turned violent on May 6 with both accusing the other of invading.
