The northern highlands of Ethiopia became a global byword for famine in the mid-1980s, when drought and conflict combined to create a disaster that killed as many as one million people. Now hunger is stalking the Tigray region again, and a senior UN official alleges that starvation is being used as a weapon of war. More than 350,000 of Tigray's nearly 6 million people are living in famine conditions, according to an analysis by United Nations agencies and global aid groups first reported by Reuters on Thursday.
