Around 10,000 people are thought to be missing following major floods in Libya according to an official from the International Federation of the Red Cross and Red Crescent Societies (IFRC).

"We can confirm from our independent sources of information that the number of missing people is hitting 10,000 so far," said Tamer Ramadan, the head of the IFRC delegation in Libya.

Widespread flooding and mudslides caused by torrential rain have destroyed many roads and homes.

The worst-affected place is the port of Derna, much of which is under water after two dams and four bridges collapsed.

"The death toll is huge and might reach thousands," added Mr Ramadan.

The IFRC could soon launch an appeal for emergency funding to support Libya's flood victims.
