The death toll from devastating floods in eastern Libya has surpassed 11,000, according to the Libyan Red Crescent.

The Libyan Red Crescent said Friday that at least 11,300 people had died and another 10,100 were reported missing.

Mediterranean storm Daniel is behind the widespread flooding in the North African nation, as it washed away entire neighborhoods over the weekend and swept bodies out to sea.

Libya's National Center of Meteorology reported that more than 16 inches of rain fell in the northeastern city of Bayda within a 24-hour period to Sunday, according to the flood tracking website Floodlist.

The nearby port city of Derna was the worst affected following the collapse of two dams, which wiped out a quarter of the area.

The city has been declared a disaster zone, with electricity and communication having been cut off, according to local officials.

A number of countries have vowed to send aid to Libya, but getting the supplies into the affected areas has proven difficult with many roads blocked and bridges destroyed.

Rescue efforts have also been hampered by the current political situation in Libya, with the oil-rich country split between two warring governments one in the east and the other in the west.

The head of the United Nation's World Meteorological Organization said Thursday that most of Libya's flooding casualties could have been avoided if the divided country had a functioning meteorological service.
