Ethiopia’s prime minister has sought to defend a major military action against the country’s defiant Tigray region Sunday, and urged citizens not to target the ethnic Tigrayan people amid fears of civil war. At least 60 people have been wounded and six killed in one location along the Tigray border alone, Doctors Without Borders said Saturday, and the United Nations warns of a major humanitarian crisis if millions flee all-out fighting or if the Tigray region remains cut off from the world. Prime Minister Abiy Ahmed tweeted that his military campaign is to bring the Tigray region to abide by Ethiopia’s “rule of law.”
