The BBC has been told that bodies are still washing up from the sea in Derna, a week after massive flash floods in Libya.

There are fears for survivors in the city of Derna with not enough medicine and clean water for those who have been made homeless.

A spokesperson for one aid organisation said trying to coordinate operations there was “a nightmare”.

One official in eastern Libya has denied allegations that many of those killed were told to stay at home, saying soldiers told people to flee.

Thousands of people were killed when two dams burst in the wake of Storm Daniel, washing away whole neighbourhoods in the city.

Figures for the number of dead vary from around 6,000 to 11,000 – and with thousands still missing, the city’s mayor says the total could reach 20,000.
