DERNA, Libya — The Libyan city of Derna has buried thousands of people in mass graves, officials said Thursday, as search teams scoured ruins left by devastating floods and the city’s mayor said the death toll could triple.
The flooding, fed by two breached dams, swept away entire families on Sunday night and exposed vulnerabilities in the oil-rich country that has been mired in conflict since a 2011 uprising that toppled long-ruling dictator Moammar Gadhafi.
Health officials have confirmed 5,500 deaths and say 9,000 people are still missing.
Here’s a look at the latest developments.
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 two dams outside the city collapsed. Floodwaters gushed down Wadi Derna, a valley that cuts through the city, crashing through buildings and washing people out to sea.
A U.N. official said Thursday that most casualties could have been avoided.
“If there would have been a normal operating meteorological service, they could have issued the warnings,” World Meteorological Organization head Petteri Taalas told reporters in Geneva. “The emergency management authorities would have been able to carry out the evacuation.”
