(AP) – Doctors who risked their lives working in Syrian hospitals described horrific conditions in the war-torn country and pleaded with U.S. lawmakers to protect and save millions of people from an escalating humanitarian crisis. They testified Wednesday before the Senate Foreign Relations Committee on the sixth anniversary of Syria’s bitter civil war, which has killed more than 400,000 people, displaced millions of others, and contributed to Europe’s worst refugee crisis since World War II. A doctor identified only as Farida told the committee she was an obstetrician in an Aleppo, Syria’s largest city, where there were body parts scattered in the streets and “blood everywhere.” For security reasons, she used only a single name and wore a medical mask covering her mouth and nose. She left Aleppo in December.
