Volkswacht Bodensee - UN warns Sudan on 'edge of abyss' as battles spark foreign exodus

But millions of Sudanese are unable to flee battles between the army and paramilitary troops clashing again in Khartoum and across the country.

They are trying to survive acute shortages of water, food, medicines and fuel as well as power and internet blackouts.

The United States and multiple European, Middle Eastern, African and Asian nations have launched emergency missions to bring to safety their embassy staff and Sudan-based citizens by road, air and sea.

At least 427 people have been killed and more than 3,700 wounded, according to UN agencies, which reported Sudanese civilians "fleeing areas affected by fighting, including to Chad, Egypt and South Sudan".

"Morgues are full. Corpses litter the streets" said Attiya Abdallah, head of the doctors' union, which on Monday reported scores more casualties after sites in south Khartoum were "heavily shelled".

UN Secretary-General Antonio Guterres warned that the violence in Sudan -- already one of the world's poorest countries, with a history of military coups -- "could engulf the whole region and beyond".

"We must all do everything within our power to pull Sudan back from the edge of the abyss," Guterres said, calling again for a ceasefire.

Britain has requested an emergency UN Security Council meeting on Sudan, which is expected to take place on Tuesday, according to a diplomat.

A UN convoy carrying 700 people completed an arduous 850 kilometre (530 mile) road trip to Port Sudan on the Red Sea coast from the capital, where they left behind gunfire and explosions.

The United Nations head of mission Volker Perthes said the convoy arrived safely.

"Thirty-five hours in a not so comfortable convoy are certainly better than three hours' bombing and sitting under the shells," he said.

A UN statement separately said he and other key staff will "remain in Sudan and will continue to work towards a resolution to the current crisis".

- 'Unspeakable destruction' -

With Khartoum airport disabled after battles that left charred aircraft on the tarmac, many foreigners were airlifted out from smaller airstrips, to countries including Djibouti and Jordan.

US special forces swooped in with Chinook helicopters Sunday to rescue diplomats and their dependents, while Britain launched a similar rescue mission.

European Union foreign policy chief Josep Borrell said more than 1,000 EU citizens had been taken out during a "long and intense weekend" involving airlift missions by France, Germany and others.

China said Monday it had "safely evacuated" a first group of citizens and would "try every means to protect the lives, properties and safety of 1,500 plus Chinese compatriots in Sudan".

The capital, a city of five million, has endured "more than a week of unspeakable destruction", Norway's ambassador Endre Stiansen wrote on Twitter after his evacuation.

He voiced "immense sadness" for colleagues and friends left behind. "I fear for their future, because at present weapons and narrow interests carry more weight than values and words."

The International Crisis Group of analysts warned the fighting threatens to "quickly plunge the country into a full-scale war embroiling countless armed groups".

One evacuee, a Lebanese man, told AFPTV upon his arrival by bus in Port Sudan that the war came "without warning".

"The situation in Khartoum in very sad ... It's destroyed. I left with this T-shirt and these pyjamas, all that I have with me after 17 years."

Those Sudanese who can afford to are also fleeing Khartoum on crowded buses on the more than 900-kilometre desert drive north to Egypt.

Among the 800,000 South Sudanese refugees who previously fled civil war in their own country, some are chosing to return, with women and children crossing the border, said the UN refugee agency.

- 'Anxiety and exhaustion' -

In the capital, army and paramilitary troops have fought ferocious street battles leaving the sky often blackened by smoke from shelled buildings and torched shops.

"There was a rocket strike in our neighbourhood ... It is like nowhere is safe," said resident Tagreed Abdin, an architect.

The fighting pits forces loyal to army chief Abdel Fattah al-Burhan against those of his deputy turned rival Mohamed Hamdan Daglo, who commands the paramilitary Rapid Support Forces (RSF).

The RSF emerged from the Janjaweed militia that then-president Omar al-Bashir unleashed in Darfur, leading to war crimes charges against Bashir and others.

The military toppled Bashir in April 2019 following mass citizen protests which raised hopes for a transition to democracy.

The two generals seized power in a 2021 coup, but later fell out, most recently over the planned integration of the RSF into the regular army.
