Although we've been reporting on the UK's planned final airlifts today, many people have been making attempts to flee the country by other means.

Chaotic scenes have been reported by a Sky News correspondent in Port Sudan, external - where people are desperate to board ships, some of which are heading to Saudi Arabia and Yemen.

Our correspondents have been in Saudi Arabia itself - and we'll bring you their dispatches shortly.

More now on those final British evacuation flights, discussed by our political correspondent a bit earlier.

All NHS doctors are now eligible to catch these, following a U-turn by the UK government.

More than 20 NHS medics with UK work permits were earlier told they couldn't do so, as they weren't British nationals. Instead they were told to make their own way back to the UK.

Only British passport holders and their dependants were allowed on flights at that time. Dr Abdulrahman Babiker - who works at a hospital in Manchester and had been visiting family in Sudan for Eid - told the BBC he felt "betrayed".

But on Friday evening, a government message sent to NHS doctors in Sudan told them to make their way to an airfield near Khartoum for evacuation. The text, seen by the BBC, told any medical staff with leave to remain to bring dependents and proof of NHS employment.

Now Dr Babiker is safe after being airlifted to Cyprus. He told the BBC he was "really glad" of the change in guidance - but pointed out there was "just one day only" for his colleagues to catch the last flights.

Using fighter jets and drones, the Sudanese military has continued to target positions in Khartoum held by the paramilitary Rapid Support Forces (RSF).

Although some neighbourhoods are quieter, it's clear the two sides are not paying much attention to the ceasefire. They blame each other for what's going on.

Tens of thousands of people are taking extremely risky journeys to reach safer parts of the country or to get out of Sudan altogether.

The only hope is that the two generals agree to negotiate.

If they don't soon, more militias are likely to take sides in this war, which would have disastrous consequences for the country and the region.

Only "a trickle" of people are now coming forward to board UK flights leaving Sudan, according to a Whitehall source.

Deputy Prime Minister Oliver Dowden will chair a Cobra meeting this afternoon in advance of the final flight at 18:00 UK time.

The evacuation process and the latest on the security situation in Sudan will be discussed.

The final UK evacuation flight from Sudan is scheduled to take off this evening.

Any British passport holders and their dependants wanting to catch a flight have been told to reach the Wadi Saedna airstrip, north of capital Khartoum, by midday local time (11:00 BST, 10:00 GMT).

Around 20 NHS doctors, without British passports, but who possess UK work permits, are now also eligible for the flights, after previously being denied access and told to find their own way to the UK.

So far, over 1,500 people have been flown out of Sudan by the UK. But the government says demand for places has now dropped.

Despite the official extension of a ceasefire by another 72 hours, fighting in Sudan is entering a third week.

• Khartoum: The Sudanese capital has been rocked by air, tanks and artillery strikes. Sudan's army has been deploying jets or drones on enemy Rapid Support Forces (RSF) troops in neighbourhoods across the capital, pinning down residents who have little power, fuel, water or food
• Cities near Khartoum: Fighting grinds on in cities near the capital, including Bahri and Ombdurman, according to Reuters news agency. In Omdurman, RSF troops have reportedly accused the army of breaking the truce with air strikes on its bases in the city
• Darfur: In the western Darfur region, the city of El Geneina has seen fighters loot and torch markets, aid warehouses and banks. Doctors say at least 74 people have been killed during two days of fighting there this week. Thousands of people are fleeing the region for their lives across the border into Chad

The fighting that erupted in Sudan on 15 April is a direct result of a vicious power struggle within the country's military leadership.

The clashes are between the regular army and a paramilitary force called the Rapid Support Forces (RSF).

Since a coup in 2021, Sudan has been run by a council of generals, led by the two military men at the centre of this dispute:

• Gen Abdel Fattah al-Burhan, the head of the armed forces and in effect the country's president

• And his deputy and leader of the RSF, Gen Mohamed Hamdan Dagalo, better known as Hemedti

They have disagreed on the direction the country is going in and the proposed move towards civilian rule.

The main sticking points are plans to include the 100,000-strong RSF into the army, and who would then lead the new force.

Today's final British flights are not the only effort by a foreign government to evacuate their citizens. The US has said several hundred Americans have left by land, sea or air.

Late on Friday, a convoy of buses carrying around 300 Americans left Khartoum on Friday, bound for Port Sudan on the Red Sea.

This was the first evacuation from Sudan involving Americans who were not diplomats. Armed drones were reportedly used to monitor and protect the convoy on its 500-mile (800km) route.

Despite the extension of a ceasefire between the warring generals by another 72 hours, fighting has continued to rock Sudan.

There have been regular airstrikes, tank and artillery strikes in parts of Khartoum and the surrounding area.

Leader of the paramilitary Rapid Support Forces (RSF) general Mohamed Hamdan Dagalo - better known as Hemedti - told the BBC his fighters were being “relentlessly” bombed since the truce had been extended. He said he would not negotiate until fighting ended.

His enemy Gen Burhan - the head of Sudan's regular army - has tentatively agreed to face-to-face talks in South Sudan. But - as our correspondent wrote below - the prospect for any wider dialogue between the warring factions seems remote.

More than 500 people have been killed and more than 4,000 wounded in the fighting, according to Sudanese health ministry figures, although the real death toll is likely much higher. Meanwhile, tens of thousands have fled for their lives.

Britain’s airlift is coming to an end.

Anyone wanting to catch a flight will need to be at the Wadi Saedna airbase, just north of Khartoum, by the middle of the day.

Over 1,500 people have been flown out of the country so far and - according to the government - demand for places has dropped.

Other evacuation operations continue. A convoy of buses carrying around 300 Americans left Khartoum yesterday, bound for Port Sudan.

The country they’re leaving behind is teetering on the edge of all-out chaos.

The latest 72-hour ceasefire, now more than a day old, is proving as patchy as the last, with parts of Khartoum and the surrounding area seeing regular air, tank and artillery strikes.

Despite international pressure to extend the truce, the prospect for any wider dialogue between the warring factions seems remote.

Thanks for joining this live page as a deadline approaches for British nationals to leave Sudan.

Fighting continues in the north-east African country in spite of the latest 72-hour ceasefire – and countries have been racing to evacuate their citizens.

The UK government says it will wind up its own evacuation efforts this evening – and has given people until midday local time (11:00 BST, 10:00 GMT) to reach an airport near the capital Khartoum if they want to fly out.

My colleague André Rhoden-Paul is sat next to me – together, we’re poised to keep you posted with the day’s developments.
