The leader of Ethiopia's rebellious Tigray region confirmed on Sunday that his forces had fired rockets at the airport in Eritrea's capital, a major escalation that raises fears of a wider war in the Horn of Africa region. Accusing neighbouring Eritrea of sending tanks and thousands of troops into Tigray in support of an Ethiopian government offensive, Debretsion Gebremichael said his forces were under attack "on several fronts." With access restricted and most communications down in Tigray, Reuters could not independently verify assertions made by all sides about the 12-day conflict.
