Peter Dut Angon, one of the "Lost Boys" of Sudan, recently travelled home to southern Sudan to visit his family, after 18 years away. He was about 10 when he had to run away.

He flew into Uganda's Entebbe Airport from Arizona in the US where he's currently living and studying.

Lack of infrastructure and poor transport links meant that Peter's journey home to the village of Marial Bai - by car, charter plane, bike and on foot - took 18 days.

"It was so exciting to be on Sudanese soil again," Peter said. "The cycling was hard-going but we took turns riding and pedalling. And when it rained, we walked!"

"Seeing my mother was like a dream - it had been so long. She cried because she had found me again." Close to 70-years-old, Ma defies the life expectancy of 58 years.

The civil war halved Peter's family. His father was killed and of 12 siblings, only six live. Peter sadly didn't see his sister who still lives in a displaced people's camp near Khartoum.

The rest though came from far and wide for the 'Welcome home' celebration. Peter said, "It was like our blood was drawing us together, bringing us to each other again."

Certain sights triggered memories of Peter's past: "This truck still stands where it was blown up. There used to be a road here but now it is bush. Landmines still cause problems."

"Since peace came, things are getting better but every way you look at it there is good and bad. The best sight for me was Sudanese military men in uniform, but without guns!"

"We need roads and communication, and then everything else will come. They are doing their best but resources are so limited. It is hard. There's a long way to go."
