(UNHCR) – In the shade of a teak tree, teenager Kenyi John sits on a mat with his four siblings and raises his arm. He throws a dice on to a colourful board and the children laugh and cheer. He has scored a six and their board game can start. Kenyi, 17, and his younger brothers and sisters are among more than 5,000 unaccompanied South Sudanese refugee children who have fled their country’s civil war and arrived in Uganda without parents. In July, they left their village with their uncle and walked for seven terrifying days until they reached the border.
