Beyonce Knowles will release her new single on World Humanitarian Day.

The 30-year-old singer's next track 'I Was Here' will be released on August 19 to mark the special remembrance day created to honor the victims of the 2003 bombing in Baghdad, Republic of Iraq.

Speaking to the United Nations assembly, Beyonce said: ''We all see the headlines and think, 'What can I really do to help?'

''World Humanitarian Day is an opportunity for all of us to work together to make a difference.''

The video for Beyonce's new hit from her latest album '4' will be a recording of her performance at the United Nations' General Assembly Rooms in New York, the Daily Express newspaper reports.

The kind-hearted superstar - who has seven-month-old Blue Ivy Carter with her rap mogul husband Jay-Z - gave a speech in front of a crowd of delegates and politicians as well as special guests Julia Stiles, producer The-Dream and Grammy Award-winning songwriter Diane Warren, who penned the track.

The day was created in 2008 to promote humanitarian efforts around the world and encourage others to do the same.
