Videos from the city of Derna show entire residential areas were erased along a river that runs down from the mountains through the city center. Tamer Ramadan, Libya envoy for the International Federation of Red Cross and Red Crescent Societies, said 10,000 people were missing after the unprecedented flooding. Entire residential blocks were erased along Wadi Derna, a river that runs down from the mountains through the city center. The storm hit other areas in eastern Libya, including the town of Bayda, where about 50 people were reported dead. Hundreds of families were displaced and took shelter in schools and other government buildings in the city of Benghazi and elsewhere in eastern Libya.
