Libya's devastating flood has transformed Derna from a busy port welcoming fishing boats and ships loaded with goods and passengers into a dump brimming with rubble, car wrecks and dead bodies. Since the tsunami-sized flood lashed Derna, port workers, fishermen and passers-by have largely abandoned the seafront. The official death toll from the disaster stands at more than 3,300 -- but the eventual count is expected to be far higher. As international aid groups struggle to provide timely humanitarian assistance to the survivors, FRANCE 24's Annette Young is joined by Dr Ahmed Zouiten, Representative of the World Health Organization (WHO) in Libya.
