The death toll from devastating flooding in Libya’s eastern coastal city of Derna has risen to at least 11,300, according to a UN report released Saturday, even as continuing search efforts are expected to find more victims.

A further 170 people have been killed outside of Derna due to the flooding, the United Nations Office for the Coordination of Humanitarian Affairs (OCHA) said.

And in Derna alone, at least 10,100 people remain missing.

“These figures are expected to rise as search-and-rescue crews work tirelessly to find survivors,” it added.

More than 40,000 people have been displaced across northeastern Libya since the extreme rainfall brought by Storm Daniel, the UN says.

At least 30,000 people have been displaced in Derna alone, the UN said.

“With thousands of displaced people now on the move, the risk of exposure to landmines and Explosive Ordnance of War (ERW) leftover from years of conflict is on the rise, as flood waters have now shifted landmines and ERW,” OCHA said.

Almost 300,000 children who were exposed to the flooding due to Storm Daniel face increased risk of cholera, malnutrition, diarrhea, and dehydration. The children also face “increased risks of violence and exploitation,” the report added.
