Alan Henning, a 47-year-old man from Eccles, England, was said to be so moved by the humanitarian crisis in Syria that he felt he had to help. The father of two, a taxi driver nicknamed "Gadget" by his friends, began working with AID4SYRIA, an Islamic charity based in Britain. He left his wife and children at home and drove with convoy to the Syrian border and beyond, delivering aid to civilians during a bloody civil war.
