SOUTH SUDAN INDEPENDENCE DAY

"Today South Sudan marks it's fourth independence anniversary and we speak to Valentino Achak one of the many children who walked for months fleeing the war. Together they became known as "the Lost Boys." He moved to America through Ethiopia and Kenya but is now back home in Northern Bahr el Ghazal state where he has set up a school and was recently named Education Minister. He told the BBC's James Copnall his story." – BBC
