Eritrean troops are still in Ethiopia although they have moved to the border between the two countries, U.S. Ambassador to the United Nations, Linda Thomas-Greenfield said on Saturday. Her remarks contradicts Ethiopian authorities who say the Eritreans have already left.  Thomas-Greenfield who was speaking at a news conference in Kenya's capital Nairobi during a visit, did not provide any evidence or source for this assessment.  Eritrea's information minister Yemane Gebremeskel did not respond to a Reuters' request for comment.
