The Sudanese Army and rival paramilitary Rapid Support Forces have signed an agreement for a seven-day ceasefire hours after air strikes hit outer areas of the Sudanese capital Khartoum.
Fighting between the two sides, who blame each other for the conflict, has led to a collapse in law and order and trapped civilians in a humanitarian crisis
The ceasefire will take effect at 9:45pm Khartoum time on Monday, the sponsors of the talks, the United States and Saudi Arabia, said in a joint statement.
Numerous previous ceasefire agreements were violated. However, this agreement will be enforced by a US-Saudi and international-supported monitoring mechanism, the statement said without providing details.
The agreement also calls for distributing humanitarian assistance, restoring essential services and withdrawing forces from hospitals and essential public facilities.
"It is past time to silence the guns and allow unhindered humanitarian access. I implore both sides to uphold this agreement. The eyes of the world are watching," US Secretary of State Antony Blinken said.
The fighting has displaced more than a million people.
Stocks of food, cash and essentials are rapidly dwindling, and mass looting has hit banks, embassies, factories and aid warehouses.
Aid groups have said they are unable to provide sufficient assistance in Khartoum, the capital, in the absence of safe passage and security guarantees for staff.
Almost 1.1 million people displaced
Air strikes were reported by eyewitnesses in southern Omdurman and northern Bahri, the two cities that lie across the Nile from Khartoum, forming Sudan's "triple capital". Some of the strikes took place near the state broadcaster in Omdurman, the eyewitnesses said.
"We faced heavy artillery fire early this morning, the whole house was shaking," Sanaa Hassan, a 33-year-old living in the al-Salha neighbourhood of Omdurman, told Reuters by phone.
"It was terrifying, everyone was lying under their beds. What's happening is a nightmare."
The RSF is embedded in residential districts, drawing almost continual air strikes by the regular armed forces.
Eyewitnesses in Khartoum said that the situation was relatively calm, although sporadic gunshots could be heard.
The conflict, which began on April 15, has displaced almost 1.1 million people internally and into neighbouring countries. Some 705 people have been killed and at least 5,287 injured, according to the World Health Organization.
In recent days, ground fighting has flared once again in the Darfur region, in the cities of Nyala and Zalenjei.
Both sides blamed each other in statements late on Friday for sparking the fighting in Nyala, one of the country's largest cities, which had for weeks been relatively calm due to a locally brokered truce.
A local activist said there were sporadic gun clashes near the city's main market close to army headquarters on Saturday morning. Almost 30 people have died in the two previous days of fighting, according to activists.
Churches, embassies among looted buildings
The war broke out in Khartoum after disputes over plans for the RSF to be integrated into the army and over the future chain of command under an internationally backed deal to shift Sudan towards democracy following decades of conflict-ridden autocracy.
On Friday, army leader General Abdel Fattah al-Burhan removed RSF chief Mohamed Hamdan Dagalo as his deputy on the ruling council they led. He replaced him with former rebel leader Malik Agar.
In a statement on Saturday, Agar said he had accepted the position to help secure peace and support for the upcoming agricultural season, whose failure would spell widespread hunger.
He said his message to the army was, "There is no alternative to peace but peace, and no way to peace other than dialogue."
"My message to the RSF is that there is no way for stability except with one united army."
The US Agency for International Development (USAID) announced late on Friday more than $US100 million ($150 million) in aid to Sudan and countries receiving fleeing Sudanese, including much-needed food and medical assistance.
"It's hard to convey the extent of the suffering occurring right now in Sudan," said agency head Samantha Power.
Among the many looted buildings in the capital are several churches, including the Virgin Mary church in downtown Khartoum, according to a church official. Armed men gave the bishop a week to vacate the church after which they looted it and set it up as their base, he said.
Church leaders have said they are not sure if attacks are targeted or part of the overall chaos gripping Khartoum.
In a statement, Qatar said that its embassy was the latest in a string of looted embassies.
