More than 2,200 people are reported dead in Libya after a storm triggered devastating floods
Much of Derna, a city home to 100,000 people, is under water after two dams and four bridges collapsed
The death toll from the city alone stands at more than 2,000, according to a minister
At least 10,000 people are missing, the International Federation of Red Cross and Red Crescent Societies says
The storm, which hit on Sunday, is also affecting the eastern cities of Benghazi, Soussa and Al-Marj.
The director of the Wahda Hospital in Derna has said that 1,700 deaths have been counted in just one hospital.
Dr Mohamad al-Qabisi, who runs the hospital in one of the areas worst-affected by the flooding, says they have been counting bodies "lying in the hallways".
"There are some who have not been identified," he adds, and also says "we started photographing and assigning numbers to them".
The death toll is expected to rise as rescue efforts continue but Dr Al-Qabisi is concerned that his staff may be limited in their ability to continue to help, due to a lack of resources and conditions.
"Things are very bad; the hospital is dilapidated," he adds.
The two rival administrations of Libya have displayed a rare sign of solidarity in their rescue and relief response to the devastation caused by Storm Daniel.
Libya's internationally recognised government which operates from the country's capital city of Tripoli, sent planes with aid supplies to the eastern part of the country which is ruled by a rival parliament, BBC Monitoring reports.
The prime minister of Libya's Tripoli-based Government of National Unity (GNU), Abdul Hamid Dbeibah, shared that a plane carrying medical personnel and 14 tonnes of supplies had been sent to the eastern city of Benghazi.
Libya's parallel parliament - the east-based House of Representatives (HoR) formed by Prime Minister Osama Hammad had originally offered separate instruction to people in his jurisdiction who have been the hardest hit by Storm Daniel.
Today's parcel of aid has been the only sign of solidarity, however, and there has been no other indication of a wider political breakthrough.
Libya's Prime Minister Abdul Hamid Al-Dbeibah earlier spoke to reporters to give an update on the situation in his country.
"We do not need aid, not even medication or equipment, nor doctors or ambulances", he said.
However, he did say "we have a problem in retrieving the bodies from the sea."
He adds that the Libyan navy, divers, and frogmen "are putting all their efforts into retrieving the bodies”.
Al-Dbeibah also said "ourselves and what were the reasons (for the flood devastation) in a calm and intelligent way".
He also confirmed that 2.5bn Libyan dinars ($515m; £413m) have been allocated "to kick off reconstruction in those areas".
