The army and the paramilitary group RSF had agreed to extend a weeklong ceasefire deal by five days just before it was due to expire on Monday.
Sudan’s army has suspended its participation in talks over a ceasefire and humanitarian access, a Sudanese diplomatic source told Al Jazeera, raising fears of renewed fighting that has displaced tens of thousands of people.
The talks with the rival paramilitary Rapid Support Forces (RSF) began in the Saudi Arabian port city of Jeddah in early May and had produced a declaration of commitments to protecting civilians and two short-term ceasefire deals that have been repeatedly violated.
The army and the RSF had agreed to extend a weeklong ceasefire deal by five days just before it was due to expire late on Monday.
Until late Tuesday, intense clashes were reported in Sudan’s capital Khartoum, with residents reporting intensive fighting in all three of the adjoining cities that make up Sudan’s greater capital around the confluence of the Nile – Khartoum, Omdurman and Khartoum North.
Al Jazeera’s Mohamed Vall said the suspension of the ceasefire was the culmination of weeks of frustration on the part of the Sudanese government.
“[The] RSF continued to violate the ceasefire and there is no meaning to this ceasefire. We still need to hear more from the army, in which they detail the reasons [as to] why they pulled out,” Vall said.
“The purpose of the talks in Jeddah was to stop the violations and help civilians reorganise their lives,” Vall added. “But that still has not happened. We have people still leaving Khartoum. We have people still trapped in their homes because [the] RSF, according to reports, is using civilians as human shields.”
The truce was brokered and is being remotely monitored by Saudi Arabia and the United States, which say it has been violated by both sides but has allowed for the delivery of aid.
The war has forced nearly 1.4 million people to flee their homes, including more than 350,000 who have crossed into neighbouring countries.
More than six weeks into the conflict, the United Nations estimated more than half the population – 25 million people – to be in need of aid and protection.
Areas of the capital have been hit by widespread looting and frequent cuts to power and water supplies. Most hospitals have been put out of service.
The UN, some aid agencies, embassies and parts of Sudan’s central government have moved operations to Port Sudan, in Sudan’s Red Sea state, the main shipping hub which has seen little unrest.
Leaders of the army and the RSF had held the top positions on Sudan’s ruling council since former leader Omar al-Bashir was toppled during a popular uprising in 2019.
They staged a coup in 2021 as they were due to hand leadership of the council to civilians, before falling out over the chain of command and restructuring of the RSF under the planned transition.
