On the Ethiopian border, refugees flee fighting, famine

Nobel Peace Prize-winner Prime Minister Abiy Ahmed of Ethiopia launched a government offensive last November against rebels in the northern region of Tigray. At the time, he promised the war would be over in a matter of weeks. But the ongoing conflict has led to thousands of deaths, displaced almost 2 million people, and led to charges of ethnic cleansing. Benedict Moran and Jorgen Samso report.
