World Humanitarian Day observed on 19 August:

World Humanitarian Day was commemorated on 19 August to honor those who risk their lives in crisis zones to assist others, and to express solidarity with millions of people facing life-threatening situations. This year’s theme highlights the severe strain on the global humanitarian system, which remains underfunded, overstretched, and often under attack. The day traces back to 19 August 2003, when a devastating bomb explosion at the UN headquarters in Baghdad killed 22 humanitarian workers, including Sergio Vieira de Mello, the UN Special Representative for Iraq. In 2008, the UN General Assembly formally recognized the day by designating 19 August as World Humanitarian Day.
