Babies in Ethiopia’s embattled Tigray region are dying in their first month of life at four times the rate before the war cut off access to most medical care for over 5 million people. That's according to the most sweeping study yet of how mothers and small children are succumbing to deprivation during the conflict. Almost two years have passed since the war cast the Tigray region into twilight, with basic services such as phone, internet and banking severed. United Nations-backed investigators last month said Ethiopia's government is using “starvation of civilians” as a weapon of war.
