Every year on 19 August, World Humanitarian Day is observed in memory of the victims of the attack on the United Nations' headquarters in Baghdad (Iraq) in 2003 which caused the death of 22 people including the UN Special Representative in Iraq Sergio Vieira de Mello.
Igal aastal tähistatakse 19. augustil ülemaailmset humanitaarabi päeva, millega mälestatakse Bagdadis (Iraagis) 2003. aastal ÜRO peakorterile korraldatud rünnaku ohvreid.
