This week’s R&D covers the violence in the Tigray region of Ethiopia.  Fighting has engulfed the area since November.  Prime Minister Abiy Ahmed ordered the country’s armed forces to go to Tigray after there was an attack on a national military base.  Tigray’s major political party governed Ethiopia’s affairs for almost thirty years until Ahmed took power in April 2018.  To date, the violence has claimed more than 8,000 lives.
