Libya floods: Up to 20,000 people dead amid catastrophic damage

International aid is slowly starting to arrive in eastern Libya - amid fears that tens of thousands are buried under mud and rubble.

Entire neighbourhoods in the city of Derna have been washed into the sea, there are shortages of food and drinking water - and relief teams are struggling to reach the worst hit areas because bridges and roads have been washed away.

So many people have died, that hospitals have been turned into makeshift morgues.
