The Libyan Red Crescent aid organization says that the death toll from floods in the eastern Libyan city of Derna has soared to 11,300.
The Secretary General of the group says a further 10,100 are reported missing in the coastal city.
Mediterranean storm Daniel caused deadly flooding in many eastern towns, but the worst-hit was Derna.
Residents said they heard loud explosions Sunday night when dams outside the city collapsed.
