Rescuers have found more than 2,000 bodies as of Wednesday in the wreckage of a Libyan city where floodwaters broke dams and washed away neighborhoods. Officials fear the death toll could exceed 5,000 in the nation made vulnerable by years of turmoil and neglect.

The flooding caused significant infrastructure damage in the coastal city of Derna and displaced at least 30,000 people, the UN migration agency said. The damage is so extensive that the city is almost inaccessible for humanitarian aid workers, the International Organisation for Migration said.
