Humanitarian Workers Face Unprecedented Violence, UN Says Lisa Schlein GENEVA - The United Nations reports humanitarian workers are facing unprecedented levels of violence while putting their own lives at risk in order to provide life-saving aid to millions of civilians caught in situations of crisis. This year's World Humanitarian Day honors and pays tribute to these thousands of unsung, real life heroes. World Humanitarian Day was created in the aftermath of the terrorist attack on the U.N. compound in Baghdad on August 19, 2003. Twenty-two people were killed, including the Secretary-General's Special Representative for Iraq, Sergio Vieiro de Mello. .
