Not On Our Watch, a charity co-founded by George Clooney, Brad Pitt, Matt Damon and Don Cheadle has donated $500,000 to the United Nations World Food Program.

The World Food Program (WFP) uses helicopters to send support people and food to northern Sudan and, more specifically, into the Darfur region that has been seen a huge influx of refugees in recent years as war ravaged the area.

“Without immediate additional funding, humanitarian aid in the region will be crippled,” Clooney said in a statement, noting that it is a critical time in Darfur. [Reuters]

Clooney has become a leading celebrity advocate for action against the genocide in the Sudan after filming a documentary about the crisis last year.
