Libya’s eastern city of Derna has buried 700 people killed in devastating flooding and 10,000 were reported missing as rescue teams struggled to retrieve many more bodies from the horrific deluge, officials said Tuesday.

Mediterranean storm Daniel on Sunday night caused havoc and flash flooding in many towns in eastern Libya but the worst destruction was in Derna, where heavy rainfall and floods broke dams and washed away entire neighborhoods, authorities said.

“The situation is catastrophic,” said Othman Abduljaleel, the health minister in Libya’s eastern government. “The bodies are still lying on the ground in many parts (of the city). Hospitals are filled with bodies. And there are areas we have yet to reach.”

Authorities estimated earlier that as many as 2,000 people may have perished in Derna alone. The Ambulance and Emergency Authority, which coordinates search and rescue efforts, said Tuesday that about 2,300 people died in Derna but did not clarify what that figure was based on.
