Tomorrow, August 19, is World Humanitarian Day, and Beyonce has been a huge supporter of it, speaking on CNN about how people can get involved, and now by releasing her official live performance video for her 4 album cut "I Was Here," which has become the anthem for tomorrow's commemorative day of service.

We already saw pics of Beyonce performing the song live at the United Nations General Assembly Hall at the video shoot, and now, it is here to enjoy in full. Hopefully this beautiful video (which was directed by Kenzo Digital) will help to bring more awareness to World Humanitarian Day. Watch above.
