Meanwhile, BBC teams in Derna say aid agencies are yet to arrive at The City .

While reporters witnessed a hive of activity in The centre of Derna - with rescuers, ambulance crews and forensic teams working to identify The Dead - There was little sign of major international aid agencies.

A spokesperson for one organisation said that trying to organise aid operations in The country was " a nightmare".

" Libya One Week ago was already complicated, " said Tomasso Della Longa from The International Federation of Red Cross and Red Crescent Societies (IFRC).

Making The Situation even more complicated - The floods have destroyed crucial infrastructure like roads and telecommunication systems.

The Death Toll varies widely, from around 6,000 up to 11,000. With many more thousands Still Missing , Derna's mayor has warned that The total could reach 20,000.

Derna's Mayor Abdulmenam al-Ghaithi told Arab news channel Al-Hadath that he " personally ordered evacuating The City three or four days before The disaster. " The Bbc has not been able to verify this.

As The Weather got worse, police and military were telling people to leave their homes for Higher Ground , survivors have told The Bbc .

But it seemed many people did not take The Threat seriously.

" A lot of them did but unfortunately, people sometimes, they said, 'well you know, this is exaggerating, this might not be The case', " Othman Abdul Jalil told The Bbc 's Newshour programme.

There are also allegations that officials took to Libyan television on Sunday Night , and ordered people to stay in their homes because of The bad weather. The Attorney General denied this, however.

It is too early to attribute with certainty The severity of This Storm to rising global temperatures.
