In 2008, the UN General Assembly adopted a resolution designating 19 August as World Humanitarian Day. This was to commemorate the 22 humanitarian workers killed in a bomb attack on the Canal Hotel in Baghdad, Iraq, on 19 August 2003, including the UN Special Representative of the Secretary-General for Iraq, Sergio Vieira de Mello.
Each year on 19 August, World Humanitarian Day advocates for the survival, well-being and dignity of people affected by crises, and for the safety and security of aid workers.
