On September 10th, Storm Daniel heavy rains caused the collapse of two dams in Derna, a coastal city in eastern Libya. Devastating floods killed at least 4,000 people within a few hours. An estimated 8,500 are still declared missing, almost three months in from the catastrophe. Since September 20th, MSF has been providing medical and mental health services to the population, to respond to one of their most crucial needs : psychological relief. “They have fear of the rain, fear of the clouds, fear of even the changing weather, and of anything that may indicate that the rain may fall again and that the flood may return again”, an MSF psychologist explains.
