We are ending our live coverage of the aftermath of the devastating floods in eastern Libya.

Before you go, take a look at a report from our correspondent on the ground, Anna Foster.

And if you want to find out how massive rescue operations are conducted, read more here.

Thank you for joining us. This page has been brought to you by Anna Foster and Mohamed Madi in Derna, and Jaime Whitehead, Ali Abbas Ahmadi, Samuel Horti, Siobhan Toman and Phelan Chatterjee in London.

When the BBC's team arrived in Derna yesterday, they described the city as a "hive of activity" - but added that international aid agencies were yet to arrive "in force".

Here's what today's rescue operation looks like, which is mainly being undertaken by local rescuers and the Libyan Red Crescent.

An Italian aid ship has arrived in Libya with tents, blankets and other materials to help survivors in Derna, but aid efforts so far have been described as "chaotic".

The World Health Organization also said it had sent medical supplies.

A spokesperson for the Tripoli based government Mohamed Hamuda - one of two rival governments in the country - said this disaster shows the need for a unified Libya.

Speaking to the Newshour programme on the BBC World Service, he said he hopes this catastrophe will help “all Libyans understand unity is the only way for us to survive, to flourish, and to move forward”.

A Maltese rescue team in Derna reported finding hundreds of bodies on Friday, the Malta Civil Protection Department (MCPD) said today.

Malta sent 72 rescuers from its army and MCPD to Libya on Wednesday.

A four person team initially found a group of seven bodies inside a cave, before discovering several hundred dead bodies and debris in a small bay.

“There were probably about 400, but’s difficult to say” the team leader said.

Our correspondent Anna Foster is in Derna reporting on the impact of the destruction almost a week on.

A spokesperson for Libya’s internationally recognised government in Tripoli says that the country’s two rival governments are working together at “middle administration level”, and had been doing so since before the floods.

Mohamed Hamuda, a spokesperson for the Government of National Unity (GNU) told Newshour on the BBC World Service that the “functional administrative authorities” have been working together nationally, and that the split between the two governments is only at a higher political level.

Officials from both the GNU and the rival Tobruk-based administration are coordinating and working together on the ground to respond to the floods, he says, but adds it is unlikely there will be a joint statement from the rival governments.

Mohamed Hamuda said that "all the governments" over the past few decades bear responsibility for the infrastructure failings that reportedly contributed to the disaster.

There is a flurry of activity in central Derna as a huge convoy of top officials reaches the stricken city centre.

Among them is Osama Hamad, the prime minister of the eastern government, along with his interior, electricity and communications ministers.

Speaking to the media, they say the storm that led to the flooding has been unprecedented, and that they’d done all they could to ensure the safe flow of aid.

But the visit was scant consolation to those who’ve lost everything.

Metres away, residents told us they felt failed and left in harm’s way.

“Why are they here?” shouts one. There is a growing anger that threatens to boil over at points.

This video, released by Libya's Almasar TV, shows the empty Wadi Derna dam which is one of the two that burst.

Libya's public prosecutor Al-Siddiq Al-Sour yesterday said that his office is investigating possible negligence by local authorities and consecutive governments.

He says the investigation includes looking at the maintenance funds that were paid to maintain the two dams.

It's been almost a week since huge flash floods destroyed Derna in the east of Libya. Here's what the city looks like today:

At a mass grave on the outskirts of the city of Derna, a cemetery worker has said they believe around 3,000 bodies have been buried on the site.

You can see overhead footage of the area in the video below.

The United Nations has said more than 1,000 people have been buried in this manner in Libya so far since deadly floods hit the country.

Aid groups and the World Health Organization are urging Libyan authorities to stop burying flood victims in mass graves located near water.

They say it could cause health risks and bring long-term distress to families.

The World Health Organization says it has sent enough health supplies to reach 250,000 people in Libya.

In a press release, external, the WHO said that 29 metric tonnes of aid- including essential medicines, trauma and emergency surgery supplies, medical equipment and body bags - have arrived in Benghazi.

The port of Benghazi is roughly 300 km away from Derna, which is difficult to get to because of destroyed roads and infrastructure.

The mental challenges for rescue workers – most of whom are from local communities – is immense, says Ahmed Bayram, the regional media and communications adviser for the Norwegian Refugee Council.

Speaking to BBC Radio Scotland earlier, Bayram said the local aid workers have faced losses themselves – in their homes and in their families. So they now face an “impossible job” - not just because of the scale of the mission following the widespread devastation, but also because of “how personal it is for them”.

Dr Margaret Harris from the World Health Organization, who was also speaking on the same programme, urged local authorities not to bury the dead in mass graves to prevent further mental trauma among the survivors.

“When you’ve got no idea what happened to your mother, your child your father, you’ll never recover from that terrible, terrible mental trauma,” she says.

Saad Rajab Mohammed Al Hassi was sitting in his living room while his wife was making dinner when the flood came into their home.

"I started to scream to God when the flood came in bringing metal, wood planks and a cement block with it”, he says.

“I looked and I saw this area all drowned in water."

Al Hassi, his wife and children ran outside to safety.

They managed to survive but their house didn't, they are now without shelter.

This is where Derna meets the sea.

And its where, even almost a week after this flooding happened, bodies are still washing up.

You can see all of the debris - there are wrecked cars, tyres, broken wood, household equipment, fridges, freezers, all kinds of things mixed together floating and bobbing in the water.

There is a rich and distinctive smell of sewage and death.

I've just been talking to a Turkish rescue team who have been here for the last 5 days.

They are walking along the front looking for bodies that come in on the waves and get trapped among all of this debris.

They say they have removed three bodies this morning from this area.

They key to rescue efforts by the International Federation of Red Cross and Red Crescent Societies (IFRC) are their local teams, says IFRC spokesperson Tomasso Della Longa.

Our national societies are our entry point, he says, which is why they are “usually the first to respond in every corner of the world,” he says.

In Libya, the Libyan Red Crescent are in touch with the international head office who then coordinate an international response, and tell foreign crews on the ground “what is needed, where to go, and how to respond”.

Partners are given a “shopping list” of what is required, and donations are transferred to the national team to procure whatever is required locally - which in turn can boost the economy just after a disaster.

Della Longa says the local Red Crescent response is crucial, as it takes longer for foreign crews to reach the stricken areas; not just because of the local infrastructure conditions, but also because they need to procure visas for all the rescue personnel and receive legal permission to bring medicines, food and other supplies.

It is astonishing when you stand in Derna and see how the centre of the city has been simply carved away; there is nothing left. Where the river ran down to the sea, there are just banks of earth and mud.

People are talking about this torrent of water having the force of an atomic bomb. Yesterday I was looking at cars that had been picked up and thrown inside buildings. Trees have been uprooted, and everything here suggests that human life has been washed away.

And you must consider that this is happening in a country which has been wracked by conflict for more than a decade, so the normal civil contingencies are not in place.

Things like tents, medical care and clean water need to be brought into the country. This is very difficult when you have these two parallel administrations controlling Libya.

And then even when you manage to get that aid into Benghazi, it is a 6-7 hour drive to Derna.

I’ve seen local Libyans with pickup trucks doing what they could. But the normal large-scale, well-rehearsed humanitarian operation from the international community that you would normally see a week after a disaster like this is not in place.

There have been widespread allegations that the two dams that collapsed were not well-maintained, and there are growing calls for an urgent inquiry into how the flooding became so catastrophic.

There are also conflicting reports as to whether - and when - people were told to flee their homes. Residents have told the BBC that they received mixed messages from the two rival governments on whether they should stay or leave.

Guma El-Gamaty, a Libyan academic and head of the Taghyeer Party, said on Thursday that people in the flood zone should have been evacuated, but "on the contrary they were told to stay put and stay inside their houses and not go out".

But Derna's mayor 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 Abdulmenam al-Ghaithi's claims.

Video footage captured across Derna shows the wide-scale destruction following the massive flash floods last weekend.
