Crisis mediation is underway to de-escalate the armed violence in Sudan after at least 56 people were killed and almost 600 injured.
Violence broke out on Saturday in the capital Khartoum and across the country as armed forces and paramilitary group Rapid Support Forces (RSF) clashed.
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.
Why has violence erupted in Sudan?
Kenyan President William Ruto and Ugandan President Yoweri Museveni have also had phone calls with General al-Burhan.
US Secretary of State Anthony Blinken has consulted with Saudi Arabian and Emirati counterparts and shared their agreement that it is “essential for all parties to immediately end hostilities”.

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.
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.
Fighting was reported around military headquarters, Khartoum International Airport and state television headquarters.
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.

Both sides signalled late on Saturday that they were unwilling to negotiate.
The military called for the RSF to be dismantled, labelling it a “rebellious militia”.
Hemedti told the satellite news network Al Arabyia that he ruled out negotiations and called on the army leader to surrender.
