Beyonce, marking the official launch of “World Humanitarian Day,” has teamed up with the United Nations for the release of her brand new “I Was Here” video.

Taped in front of a live audience at the U.N. General Assembly earlier this month, the music video for “I Was Here,” a song, written by Diane Warren, from Beyonce’s most recent album “4,” features the singer dressed in a long, flowing, sparkling white dress in front of a huge screen projecting images of humanitarian efforts all over the world.

According to a video posted on the UN website and Beyonce’s official site, World Humanitarian Day — which was officially observed Sunday (Aug 19) — is a “time to recognize those who face danger and adversity in order to help others” and was “designated by the General Assembly to coincide with the anniversary of the 2003 bombing of the United Nations headquarters in Baghdad, Iraq, which killed 22 UN staff.”
