The White Helmets, officially known as the Syria Civil Defence, is a humanitarian organisation made up of 3,400 volunteers – former teachers, engineers, tailors and firefighters – who rush to pull people from the rubble when bombs rain down on Syrian civilians. They’ve been credited with saving thousands of civilians during the country’s continuing civil war.
They have also exposed, through first-hand video footage, war crimes including a chemical attack in April. Their work was the subject of an Oscar-winning Netflix documentary and the recipient of two Nobel peace prize nominations.
