"Beyonc\u00C3\u00A9 performed at the United Nations in New York on Friday (August 10). According to the  BBC, the star sang &amp;#039;I Was Here&amp;#039; from her album 4 in front of fellow celebrities and UN officials to mark World Humanitarian Day.  The live performance was recorded and will be made into a video that is due to be released globally on World Humanitarian Day (August 19). It is to be used to launch a global campaign encouraging people to do something good for those in need. &amp;quot;We all see the headlines and we think, &amp;#039;What can I really do to help?&amp;#039;,&amp;quot; said Knowles in a statement before the event.   &amp;quot;World Humanitarian Day is an opportunity for all of us to work together to make a difference. This is our time to leave our mark on the world and show that we were here and we care.&amp;quot; Stars in attendance on Friday included actress Julia Stiles, R&amp;amp;B singer The-Dream and Diane Warren, who wrote the song. Prior to her performance, Beyonc\u00C3\u00A9 also met with United Nations leader Ban Ki-moon. &amp;quot;I hope everyone will pledge to complete at least one humanitarian action - however great or small,&amp;quot; added UN aid chief Valerie Amos. &amp;quot;Together we can create an unprecedented awareness of the plight of people affected by crises around the world.&amp;quot; The UN General Assembly declared August 19 World Humanitarian Day in 2008, with the aim to recognise people who risk their lives to help those in need. The date marks the day in 2003 when 22 people were killed in a bomb attack on UN offices in Baghdad.
