CAIRO >> Emergency workers uncovered hundreds of bodies in the wreckage of Libya’s eastern city of Derna today, and it was feared the toll could spiral with 10,000 people reported still missing after floodwaters smashed through dams and washed away entire neighborhoods of the city.

The startling death and devastation wreaked by Mediterranean storm Daniel pointed to the storm’s intensity, but also the vulnerability of a nation torn apart by chaos for more than a decade. The country is divided by rival governments, one in the east, the other in the west, and the result has been neglect of infrastructure in many areas.

Outside help was only just starting to reach Derna today, more than 36 hours after the disaster struck. The floods damaged or destroyed many access roads to the coastal city of some 89,000.

Footage showed dozens of bodies covered by blankets in the yard of one hospital. Another image showed a mass grave piled with bodies. More than 1,000 corpses were collected, including at least 700 that have been buried so far, the health minister for eastern Libya said. Derna’s ambulance authority put the current death toll at 2,300.

But the toll is likely to be higher, in the thousands, said Tamer Ramadan, Libya envoy for the International Federation of Red Cross and Red Crescent Societies. He told a U.N. briefing in Geneva via videoconference from Tunisia that at least 10,000 people were still missing.

The situation in Libya was “as devastating as the situation in Morocco,” Ramadan said, referring to the deadly earthquake that hit near the city of Marrakesh on Friday night.

The destruction came to Derna and other parts of eastern Libya on Sunday night. As the storm pounded the coast, Derna residents said they heard loud explosions and realized that dams outside the city had collapsed. Flash floods were unleashed down Wadi Derna, a river running from the mountains through the city and into the sea.

The wall of water “erased everything in its way,” said one resident, Ahmed Abdalla.

Videos posted online by residents showed large swaths of mud and wreckage where the raging waters had swept away neighborhoods on both banks of the river. Multi-story apartment buildings that once were well back from the river had facades ripped away and concrete floors collapsed. Cars lifted by the flood were left dumped on top of each other.

Local emergency responders, including troops, government workers, volunteers and residents dug through rubble today looking for the dead. They also used inflatable boats to retrieve bodies from the water.

Many bodies were believed trapped under rubble or had been washed out into the Mediterranean Sea, said eastern Libya’s health minister, Othman Abduljaleel.

“We were stunned by the amount of destruction … the tragedy is very significant, and beyond the capacity of Derna and the government,” Abduljaleel told The Associated Press on the phone from Derna.

Red Crescent teams from other parts of Libya also arrived in Derna this morning but extra excavators and other equipment had yet to get there.

Flooding often happens in Libya during rainy season, but rarely with this much destruction. A key question was how the rains were able to burst through two dams outside Derna — whether because of poor maintenance or sheer volume of rain.

Karsten Haustein, a climate scientist and meteorologist at Leipzig University, said in a statement that Daniel dumped 440 millimeters (15.7 inches) of rain on eastern Libya in a short time.

“The infrastructure could probably not cope, leading to the collapse of the dam,” he said, adding that human-induced rises in water surface temperatures likely added to the storm’s intensity.

Local authorities have neglected Derna for years. “Even the maintenance aspect was simply absent. Everything kept being delayed,” said Jalel Harchaoui, an associate fellow specializing in Libya at the London-based Royal United Services Institute for Defense and Security Studies.

Factionalism also comes into play. Derna was for several years controlled by Islamic militant groups. Military commander Khalifa Hifter, the strongman of the east Libya government, captured the city in 2019 only after months of tough urban fighting.

The eastern government has been suspicious of the city ever since and has sought to sideline its residents from any decision-making, said Harchaoui. “This mistrust might prove calamitous during the upcoming post-disaster period,” he said.

Hifter’s eastern government based in the city of Benghazi is locked in a bitter rivalry with the western government in the capital Tripoli. Each is backed by powerful militias and by foreign powers. Hifter is also backed by Egypt, Russia, Jordan and the United Arab Emirates, while the west Libya administration is backed by Turkey, Qatar and Italy.

Still, the initial reaction to the disaster brought some crossing of the divide.

The Tripoli-based government of western Libya sent a plane with 14 tons of medical supplies and health workers to Benghazi. It also said it had allocated the equivalent of $412 million for reconstruction in Derna and other eastern towns. Airplanes arrived this in Benghazi carrying humanitarian aid and rescue teams from Egypt, Turkey and the United Arab Emirates. Egypt’s military chief of staff also met with Hifter to coordinate aid.

It was not clear how quickly the aid could be moved to Derna, 150 miles east of Benghazi, given conditions on the ground. Ahmed Amdourd, a Derna municipal official, called for a sea corridor to deliver aid and equipment.

U.S. Special Envoy for Libya Richard Norland said on X platform, formerly known as Twitter, that the United States is coordinating with the United Nations and local authorities to assess how best to target official U.S. assistance.

The storm hit other areas in eastern Libya, including the town of Bayda, where about 50 people were reported dead. The Medical Center of Bayda, the main hospital, was flooded and patients had to be evacuated, according to footage shared by the center on Facebook.

Other towns that suffered included Susa, Marj and Shahatt, according to the government. Hundreds of families were displaced and took shelter in schools and other government buildings in Benghazi and elsewhere in eastern Libya.

Northeast Libya is one of the country’s most fertile and green regions. The Jabal al-Akhdar area — where Bayda, Marj and Shahatt are located — has one of the country’s highest average annual rainfalls, according to the World Bank.
