In an effort to encourage people around the world to make a difference, singer Beyonce Knowles has teamed up with the United Nations for her latest music video.

"I Was Here" was taped in front of a live audience at the U.N. General Assembly on Aug. 10 and was posted on her website on Saturday to coincide with World Humanitarian Day - which is observed today.

The video features Beyonce dressed in a long flowing white dress in front of a large screen that projected images of humanitarian workers.

The inspirational song features lyrics such as, "The hearts I have touched, will be the proof that I leave that I made a difference, and this world will see."

World Humanitarian Day is a "time to recognize those who face danger and adversity in order to help others. The day 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," according to the video posted on the UN website and singer's site.

Beyonce said she was attracted to "raising awareness of this day of recognition."

"I found out that 22 people lost their lives helping people (in Baghdad). I thought it was such an incredible thing to turn that into something positive and try to include the world into doing something great for someone else," the singer said in a video posted on the UN website. "I feel like we all want to know that our life meant something and that we did something for someone else and that we spread positivity, no matter how big or how small."

UN Under-Secretary-General for Humanitarian Affairs and Emergency Relief Coordinator Valerie Amos said the day is both a commemoration and a "celebration of things that people do."

"There's an amazing amount that people do every single day that goes unrecognized. This is about the big things and it's also about the small things," Amos said in the UN video.
