(Huffington Post) – Fourteen years ago, on August 19, 2003, a suicide bomber drove a truck bomb into the offices of the United Nations Assistance Mission in Iraq, killing 22 people, wounding over 100, and damaging a nearby hospital. In tribute to aid workers risking their lives in service, the UN General Assembly designated August 19 as World Humanitarian Day. Yet, in conflicts throughout the world, warring parties continue to target humanitarians and hospitals as a tactic of war.
