Derna has begun burying its dead, mostly in mass graves, said eastern Libya’s health minister, Othman Abduljaleel More than 3,000 bodies were buried by Thursday morning, the minister said, while another 2,000 were still being processed DERNA, Libya: The city of Derna has buried thousands of people in mass graves, Libyan officials said Thursday, as search teams scoured ruins left by devastating floods and the city’s mayor said that the death toll could triple. The deluge swept away entire families on Sunday night and exposed vulnerabilities in the oil-rich country that has been mired in conflict since the 2011 uprising that toppled Muammar Qaddafi. Health officials have confirmed 5,500 deaths and say 9,000 people are still missing. WHAT HAPPENED IN LIBYA? Daniel, an unusually strong Mediterranean storm, caused deadly flooding in towns across eastern Libya, but the worst-hit was Derna. As the storm pounded the coast Sunday night, residents said they heard loud explosions when the dams outside the city collapsed. Floodwaters washed down Wadi Derna, a valley that cuts through the city, crashing through buildings and washing people out to sea. The World Meteorological Organization said earlier this week that the National Meteorological Center had issued warnings 72 hours before the flooding, notifying all governmental authorities by email and through media. It was not immediately clear whether or how those warnings were acted upon. HOW DOES CONFLICT IN LIBYA AFFECT THE DISASTER? The startling devastation reflected the storm’s intensity, but also Libya’s vulnerability. Oil-rich Libya has been divided between rival governments for most of the past decade — one in the east, the other in the west — and one result has been widespread neglect of infrastructure. The dams that collapsed outside Derna were built in the 1970s and have not been maintained for years, local media reported. The disaster brought a rare moment of unity, as government agencies across the country rushed to help the affected areas. While the Tobruk-based government of east Libya is leading relief efforts, the Tripoli-based western government allocated the equivalent of $412 million for reconstruction in Derna and other eastern towns, and an armed group in Tripoli sent a convoy with humanitarian aid. WHAT’S HAPPENING TODAY? Derna has begun burying its dead, mostly in mass graves, said eastern Libya’s health minister, Othman Abduljaleel. More than 3,000 bodies were buried by Thursday morning, the minister said, while another 2,000 were still being processed. He said most of the dead were buried in mass graves outside Derna, while others were transferred to nearby towns and cities. Abduljaleel said rescue teams were still searching wrecked buildings in the city center, and divers were combing seawater off Derna. Untold numbers could be buried under drifts of mud and debris, including overturned cars and chunks of concrete, that rise up to four meters (13 feet) high. Rescuers have struggled to bring in heavy equipment as the floods washed out or blocked roads leading to the area. HOW MANY PEOPLE HAVE BEEN KILLED? Health authorities have put the death toll in Derna at 5,500 as of Thursday morning. The number of deaths was likely to climb as searches are continuing, and at least 9,000 people are still missing, said Ossama Ali, a spokesman for an ambulance center in eastern Libya. “Some bodies may not be found, especially those who were swept out to sea,” he said. Local officials suggested that the death toll could be much higher than announced. In comments to Al Arabia television, Derna Mayor Abdel-Moneim Al-Ghaithi said the tally could climb to 20,000, given the number of neighborhoods that were washed out. An official with the UN’s World Health Organization in Libya said the fatalities could reach 7,000, given the number of people who were still missing. The official was not authorized to brief media and spoke on condition of anonymity. The storm also killed around 170 people in other parts of eastern Libya, including the towns of Bayda, Susa, Um Razaz and Marj, the health minister said. The dead in eastern Libya included at least 84 Egyptians, who were transferred to their home country on Wednesday. More than 70 came from one village in the southern province of Beni Suef. Libyan media also said dozens of Sudanese migrants were killed in the disaster. IS HELP REACHING SURVIVORS? The floods have also displaced at least 30,000 people in Derna, according to the UN’s International Organization for Migration, and several thousand others were forced to leave their homes in other eastern towns, the UN agency said. The floods damaged or destroyed many access roads to Derna, hampering the arrival of international rescue teams and humanitarian assistance. Local authorities were able to clear some routes, and over the past 48 hours humanitarian convoys have been able to enter the city. The International Committee of the Red Cross said Thursday it has provided 6,000 body bags to local authorities, as well as medical, food and other supplies distributed to hard-hit communities. International aid started to arrive earlier this week to Benghazi, 250 kilometers (150 miles) west of Derna. Neighboring Egypt, Algeria and Tunisia have sent rescue teams and aid, as did Turkiye, Italy and the United Arab Emirates. The UK and German governments have also sent supplies. President Joe Biden said the United States would send money to relief organizations and coordinate with Libyan authorities and the United Nations to provide additional support.
