[VOA] Tension between Amhara and Tigray, two of Ethiopia's most powerful regions, is increasing as the country approaches elections next year, says a new International Crisis Group report. The northern Tigray region, which ruled the country for nearly three decades, has been ostracized by the federal government in Addis Ababa, raising the risk of military conflict in the north. The two regions also share a contested border and are at odds over when federal elections should be held.
