The World Humanitarian Day is observed annually on Aug. 19.
It is to pay tribute to aid workers who risk their lives in humanitarian service, and rally support for people affected by crises worldwide.
It was designated by the General Assembly to coincide with the date of the 2003 bombing of the UN headquarters in Baghdad, Iraq, in which 22 staff were killed.
The UN chief expressed regret that 65 million civilians were currently uprooted from their homes as a result of crises.
Armed conflicts are tearing communities and countries apart, forcing record numbers of people from their homes to rely on humanitarian aid for their survival and protection.
Every year on World Humanitarian Day, the UN shines a spotlight on the millions of civilians around the world whose lives have been caught up in conflict.
On this day, people also take a moment to honour the brave health and aid workers who are targeted or obstructed as they set out to help people in need.
This year, on World Humanitarian Day, UN and partners were calling on all global leaders to do everything in their power to protect people caught up in conflict.
