In May this year in Goma, a city in the east of the Democratic Republic of Congo, a volcano erupted. "In the chaos that followed, families fleeing the eruption became separated," says this article and accompanying video from BBC News. "Two months on and many people are still living in temporary camps, unable to return to their homes, and some children still haven't found their families." The video highlights the work of one young local woman, Sarah, who works with street children, who has made it her mission to reunite children and parents.
