Every day, humanitarian aid workers stand on the front lines of war and disaster, braving tremendous dangers and difficulties to deliver assistance to those who need it most. World Humanitarian Day (WHD), which takes place every year on 19 August, recognizes the aid workers who risk their lives in humanitarian service, and mobilizes people to advocate for humanitarian action. The day was designated by the General Assembly to coincide with the anniversary of the 2003 bombing of the United Nations headquarters in Baghdad, Iraq.
