A familiar sight to children playing in the dusty lanes of Jordan's Zaatari and Azraq refugee camps, Mustafa Hassan, an International Rescue Committee aid worker, from Sudan, is a calming presence amid the chaos and ravages of war.
A father figure to the camp's young Syrian refugees Mustafa Hassan is taken for comfort and advice. TIME magazine named him, in 2015, one of the world's 100 most influential people for his tireless efforts to protect the youngest victims of Syria's civil war. Mustafa and the 50 members of his child-protection team do the painstaking detective work necessary to help children separated from their families reunite with relatives.
