(AFP) – Their hug is long and moving but awkward as Jorgina, sobbing, strains to embrace her teenage son Emmanuel who has grown taller since South Sudan’s war tore them apart. It has been three and a half years since they last saw each other. They’ve both been shunted to and fro by the relentless fighting. Emmanuel is now a gangly two metre (6.5 foot) tall 17-year-old. He and Jorgina are among thousands of family members who lost sight of each other in the chaos of the civil war in the new African nation that just gained independence from Sudan in 2011. More than 3.7 million people have been forced to flee their homes since the war started in December 2013.
