Beyonce hit the stage at the United Nations Headquarters in New York City Friday night, where she shot the video for her new single “I Was Here” to promote the launch of World Humanitarian Day.

Dressed in a long-sleeved, figure-hugging all white dress, the charitable singer wowed the audience in the UN’s General Assembly Room as screens behind her showed images of different regions around the world that has been struck by disaster or famine, interlaced with the faces of humanitarian workers.

Anderson Cooper also hosted a series of interviews with local and international humanitarians before eventually introducing Beyonce’s performance.

World Humanitarian Day is a day of remembrance set up for the victims of a 2003 Baghad bombing, and a day to promote humanitarian efforts all over the world.

Beyonce has teamed up with UN officials to launch the global initiative, and the “I Was Here” video will be released on August 19th to mark the official launch of World Humanitarian Day, which is encouraging over a billion people worldwide to give back to their local communities by getting involved in charity ventures.
