NEW YORK - Beyonce is teaming with the United Nations and humanitarian aid organizations on a global campaign to encourage people around the world to get involved.

The international pop star and songwriter Diane Warren will donate a video of "I Was Here" that will be filmed in the UN General Assembly Hall in New York in front of a live audience. The video will premiere Aug. 19 on World Humanitarian Day and the UN hopes it will help the campaign reach 1 billion people.

A news release says the campaign website launched Thursday and allows people to share individual acts of good.

Beyonce says in the statement that World Humanitarian Day is a chance to work together and "this is our time to leave our mark on the world."
