[Addis Standard] Addis Abeba -- The U.S. Special Envoy for the Horn of Africa, Mike Hammer, told media this afternoon that the U.S. was "tracking" recent Eritrean troop movements along the Ethiopian border. The Envoy's remark came shortly after Tigrayan authorities said that "Eritrean forces have launched full scale offensive in all fronts today," and days after news reports emerged that Eritrea was "mobilizing" its military reservist.
