ALEPPO, Syria — LAST week, Syrian or Russian jets bombed Al Quds hospital, in the eastern part of the divided city of Aleppo. At least 50 people lost their lives, and some 80 more were injured.

Among those killed in the attack was my dear friend and colleague, Dr. Muhammad Wassim Mo’az, a kind man who cared deeply for his patients and his community. He slept in the hospital in case there was an emergency and he had to rush to treat babies and children. He was the last pediatrician in Aleppo.
