Background

On 19 August 2003, a terrorist attack hit the United Nations headquarters in Baghdad, killing 22 people. Among those who lost their lives was Sergio Vieira de Mello, the UN’s top representative in Iraq.

Five years later, the General Assembly adopted a resolution designating 19 August as World Humanitarian Day. Every year since then, the humanitarian community has organized global campaigns to commemorate WHD, advocating for the safety and security of humanitarian aid workers, and for the survival, well-being and dignity of people affected by crises.
