Three UN World Food Programme (WFP) workers were among those killed in clashes in Darfur.
Two more employees were injured while carrying out duties and a humanitarian aircraft was damaged, “seriously impacting” WFP’s work, a spokesperson said.
The programme has paused while security is reviewed as the spokesperson said there was “no excuse for targeting humanitarian workers”.
Tensions had been escalating between army head and de facto president Abdel Fattah al Burhan and RSF chief Mohamed Hamdan Dagalo, better known as Hemedti.
South Sudan President Salva Kiir and Ethiopian prime minister Abiy Ahmed have had phone calls with both leaders in an attempt to calm the violence.
Egypt and South Sudan have offered to mediate between the army and paramilitary.
Kenyan President William Ruto and Ugandan President Yoweri Museveni have also had phone calls with General al Burhan.

US Secretary of State Antony Blinken has consulted with Saudi Arabian and Emirati counterparts and shared their agreement that it is “essential for all parties to immediately end hostilities”.
The two groups continued their battle for control on Sunday, signalling they were unwilling to end hostilities despite mounting diplomatic pressure.
Heavy fighting involving armoured vehicles, truck-mounted machine guns and war planes raged on Sunday in the capital of Khartoum, its sister city of Omdurman and in flashpoints across the country.
Sudan waits to see how high the price of peace will be
There are no heroes in this story.
Both the army and Rapid Support Forces (RSF) have been responsible for committing atrocities against civilians. Hundreds have been killed since the 2019 revolution and many more injured.
Now, the power pact that brought the two sides together to consolidate state power in the face of a pro-democracy movement has crumbled and Sudan’s citizens are once again caught in the crossfire.
Nowhere has this been felt more than in Darfur.
The RSF is made up of militias that terrorised civilians in the Darfur conflict that started in 2003 and is headed up by Mohamed Hamdan Dagalo, known as Hemedti.
During the post-revolution period, Hemedti has been de-facto vice president to his current opponent commander-in-chief Abdel Fattah al-Burhan.
Since 2020, Hemedti’s troops have been officially charged with maintaining Darfur’s security. In this time, hundreds have been killed in communal clashes and border incursions with the Central African Republic.
At least 22 civilians have been killed in the southern Darfuri city of Nyala where the RSF has full control of the airport.
Darfur Monitors told Sky News from the ground that a majority of the casualties died of internal bleeding from stray artillery as the army and RSF fought for control.
Nyala’s main hospital currently has no electricity and little capacity to help the wounded. Fighting has started in a strategic point in the city where residents are most vulnerable and hundreds more could be killed.
The death toll from Khartoum is also steadily rising. The capital is a key battleground in the fight for symbolic power and is shaken by the explosive confrontations. Here, the army is also notorious for human rights abuses and ruling the country by default.
The streets of Khartoum have been home to mass protests calling for an end to military rule and transition to civilian authority – only to be dispersed with deadly gunfire and tear gas.
International mediation has come for all sides – the UN, UK, US, EU, African Union (AU) and Intergovernmental Authority on Development (IGAD) – to transition the country into democracy but drafted power-sharing framework agreements have been signed, although not sustained.
Now, the country waits to see which side will emerge victorious and how high the price of peace will be.
Fighting was reported around military headquarters, Khartoum International Airport and state television headquarters, prompting the channel to cut transmission.
A senior military official said RSF fighters clashed with troops at military headquarters early on Sunday and that a fire broke out at a facility for ground troops.

What’s going on in Sudan?
Former Sudanese prime minister Abdalla Hamdok said: “Peace remains the only feasible choice for the people of Sudan to avoid plunging the country into a civil war.
“We all witnessed the consequences of a civil war in many regions in Africa and in the Arab world. We must avoid that, and we can still avoid such a catastrophic situation. Therefore, I call for an immediate ceasefire and to reach an agreement, which leads to a permanent cessation (of hostilities).”
He also added other countries should not intervene in any negotiations.
Both sides signalled late on Saturday that they were unwilling to negotiate, but on Sunday a statement from the UN said General al Burhan and Hemedti agreed to a proposal for a three-hour pause in fighting (from 2pm to 5pm GMT), to allow the safe passage of humanitarian cases.
Despite the agreement, gunfire could be heard and plumes of smoke seen in the background of live broadcasts.
Hemedti previously told the satellite news network Al Arabiya that he ruled out negotiations and called on the army leader to surrender.
The military called for the RSF to be dismantled, labelling it a “rebellious militia”.
Nine of a doctor’s 10 children have been killed in an Israeli missile strike on their home in Gaza, which also left her surviving son badly injured and her husband in a critical condition.
Warning: This article contains details of child deaths
Alaa Al Najjar, a paediatrician at Al Tahrir Clinic in the Nasser Medical Complex, was at work during the attack on her home, south of the city of Khan Younis in southern Gaza, on Friday.
Graphic footage shared by the Hamas-run Palestinian Civil Defence shows the bodies of at least seven small children being pulled from the rubble.
Rescuers can be seen battling fires and searching through a collapsed building, shouting out when they locate a body, before bringing the children out one by one and wrapping their remains in body bags.
In the footage, Dr Al Najjar’s husband, Hamdi Al Najjar, who is also a doctor, is put on to a stretcher and then carried to an ambulance.
The oldest of their children was only 12 years old, according to Dr Muneer Alboursh, the director general of Gaza’s health ministry, which is run by Hamas.

“This is the reality our medical staff in Gaza endure. Words fall short in describing the pain,” he wrote in a social media post.
“In Gaza, it is not only healthcare workers who are targeted – Israel’s aggression goes further, wiping out entire families.”

British doctors describe ‘horrific’ and ‘unimaginable’ attack
Two British doctors working at Nasser Hospital described the attack as “horrific” and “unimaginable” for Dr Al Najjar.
Speaking in a video diary on Friday night, Dr Graeme Groom said his last patient of the day was Dr Al Najjar’s 11-year-old son, who was badly injured and “seemed much younger as we lifted him on to the operating table”.

The strike “may or may not have been aimed at his father”, Dr Groom said, adding that the man had been left “very badly injured”.
Dr Victoria Rose said the family “lived opposite a petrol station, so I don’t know whether the bomb set off some massive fire”.

‘No political or military connections’
Dr Groom added: “It is unimaginable for that poor woman, both of them are doctors here.
“The father was a physician at Nasser Hospital. He had no political and no military connections. He doesn’t seem to be prominent on social media, and yet his poor wife is the only uninjured one, who has the prospect of losing her husband.”

Nineteen of Gaza’s hospitals remain operational, all of them are overwhelmed with the number of patients and a lack of supplies
He said it was “a particularly sad day”, while Dr Rose added: “That is life in Gaza. That is the way it goes in Gaza.”
Sky News has approached the Israeli Defence Forces for comment.
Israel’s war against Hamas in Gaza began when the militant group stormed across the border into Israel on 7 October 2023, killing some 1,200 people, most of them civilians, and abducting 251 others.
Israel’s military response has flattened large areas of Gaza and killed more than 53,000 Palestinians, mostly women and children, according to Gaza’s Hamas-run health ministry, which does not differentiate between civilians and combatants in its count.
The head of the UN has said Israel has only authorised for Gaza what amounts to a “teaspoon” of aid after at least 60 people died in overnight airstrikes.
UN secretary general Antonio Guterres said on Friday the supplies approved so far “amounts to a teaspoon of aid when a flood of assistance is required,” adding “the needs are massive and the obstacles are staggering”.
He warned that more people will die unless there is “rapid, reliable, safe and sustained aid access”.

Gaza: ‘Loads of children with huge burns’
Israel says around 300 aid trucks have been allowed through since it lifted an 11-week blockade on Monday, but according to Mr Guterres, only about a third have been transported to warehouses within Gaza due to insecurity.
The IDF said 107 vehicles carrying flour, food, medical equipment and drugs were allowed through on Thursday.
Many of Gaza’s two million residents are at high risk of famine, experts have warned.
Meanwhile, at least 60 people have been killed by Israeli airstrikes across Gaza overnight.

‘Almost everyone depends on aid’ in Gaza
The latest strikes came a day after two Israeli embassy workers were killed in Washington.
The suspect, named as 31-year-old Elias Rodriguez from Chicago, Illinois, told police he “did it for Gaza”.
Israeli Prime Minister Benjamin Netanyahu accused Sir Keir Starmer, Emmanuel Macron and Mark Carney of fuelling antisemitism following the shootings.
Mr Netanyahu also accused Sir Keir, Mr Macron and Mr Carney of siding with “mass murderers, rapists, baby killers and kidnappers”.

But UK government minister Luke Pollard told Sky News on Friday morning he “doesn’t recognise” Mr Netanyahu’s accusation.
Earlier this week, Mr Netanyahu said he was recalling negotiators from the Qatari capital, Doha, after a week of ceasefire talks failed to bring results. A working team will remain.
The war in Gaza began when Hamas-led militants attacked southern Israel on 7 October 2023, killing some 1,200 people, mostly civilians, and kidnapping 251 others.
