Officials in eastern Libya have reported that over 2,000 people may have been killed and thousands more are missing after a powerful storm caused devastating flooding. The head of Libya’s eastern Parliament-backed government, Osama Hamad, stated that the city of Derna has become a disaster zone after dams collapsed, leading to buildings and homes being swept away. The flooding has made Derna virtually inaccessible. Libya’s eastern-based Parliament has declared three days of mourning in all affected cities. The Libyan National Army (LNA), which controls eastern Libya, estimates that the death toll could be in the thousands with around 5,000-6,000 currently missing in Derna. The Red Crescent in Benghazi had earlier reported an estimated death toll of 150 but expects it to rise to 250 after multiple building collapses during the storm. The situation is described as “very catastrophic.” Storm Daniel, also known as Cyclone Daniel, made landfall on September 10 and caused severe weather conditions in several cities in Libya. Rainfall measurements show that Derna experienced 170 mm (6.7 inches) of rain on September 10 and 73 mm (2.9 inches) on September 11. Bayda received 414.1 mm (16.3 inches) of rain, and Marawah in the District of Jabal al Akhdar saw 240 mm (9.4 inches) on September 10. The storm also caused deaths in other towns, with at least 46 reported in Bayda and seven in Susa. The towns of Shahatt, Omar al-Mokhtar, and Marj also reported deaths. Videos and images shared by Libya’s Almostakbal TV show collapsed buildings and homes, as well as people stranded on the roofs of their vehicles in the flooded streets. Libya has been divided between rival administrations in the east and west since 2014, following the uprising against Moammar Gadhafi in 2011. The head of the Tripoli-based unity government, Abdul Hamid Dbeibeh, has declared the affected areas as “disaster zones.” Search-and-rescue efforts are ongoing. The US Embassy in Libya is coordinating with the United Nations and Libyan authorities to provide assistance. Storm Daniel also caused fatalities in Greece, Turkey, and Bulgaria.
