A proxy war between Iran-backed Houthi rebels and a Saudi Arabia-led coalition has led to starvation and blocked supplies to the poorest country in the region. NewsHour Weekend Special Correspondent Marcia Biggs reports on severe malnutrition in Yemen and the challenges aid workers face there. The piece was produced in partnership with the Pulitzer Center on Crisis Reporting.
