Hollywood couple Angelina Jolie and Brad Pitt have donated $100,000 (£51,000) to a medical clinic in Sudan.
Jolie and Pitt found out about the clinic at a film premiere
The Duk Lost Boys Clinic is the first of its kind in south Sudan's Duk County and will serve more than 150,000 people when it opens later this spring.
The clinic is the brainchild of John Dau, one of the "lost boys" in the film God Grew Tired of Us, produced by Pitt.
The film tells of 25,000 boys who fled war-torn Sudan, travelling for five years to get to a Kenyan refugee camp.
Almost 4,000 of them, including Mr Dau, then emigrated to the US.
The clinic is situated in the village Mr Dau initially fled during an attack by pro-government forces.
"Angelina Jolie and Brad Pitt demonstrate the American spirit of generosity," he said.
Southern Sudanese rebels spent decades fighting the government
"Hopefully their donation will inspire others to join with us to rebuild southern Sudan."
South Sudan has hardly any infrastructure following a 21-year conflict between southern rebels and the northern government.
A peace deal was signed to end the war in 2005.
The documentary, on which Pitt was executive producer, won the grand jury prize at the Sundance Film Festival last year.
Jolie and Pitt, who have four children, learned of Mr Dau's clinic when they attended the film's Hollywood premiere in January.
The donation will come from the Jolie-Pitt Foundation, which they set up to help humanitarian causes around the world.
In addition, volunteers from charity Direct Change have raised $340,000 (£173,000) towards the clinic, while volunteers for the American Care for Sudan Foundation in Syracuse, New York, have helped to construct the building.
