“The Saudi and US facilitators noted that neither side observed its commitment not to seek military advantage during the 48-hour period after the agreement was signed and before it went into effect,” the Saudi foreign ministry said in a statement.

Over the past weeks, the US and Saudi Arabia have been mediating in talks between the warring sides, held in the kingdom. A new truce was announced over the weekend — the seventh attempt so far to stop the deadly violence in the east African nation. It went into effect on Monday night.

All previous ceasefires were violated.

“While fighting in Khartoum appeared to be less intense than in recent days, the facilitators have conveyed to the parties’ reports indicating that both sides violated the ceasefire, including offensive operations in Khartoum and El-Obeid, airstrikes, and use of artillery,” the Saudi statement added.

The statement also revealed that: "Representatives of the Follow-up and Coordination Committee today in Jeddah engaged in constructive discussions about humanitarian aid and its delivery, and worked to include the leaders of the two sides to talk about allegations of violations of the ceasefire, and to work to deliver humanitarian aid to provide relief to the needy.”

Meanwhile, US Secretary of State Antony Blinken on Tuesday warned Sudan's rivals to abide by the latest ceasefire or face possible sanctions, as residents reported sporadic fighting between the two sides in the capital Khartoum and a northern city.

In a video message posted by the US embassy on social media early Tuesday, Blinken said the fighting has been “tragic, senseless, and devastating.”

The truce, he said, is to allow the delivery of humanitarian assistance and restore essential services and infrastructure destroyed in the clashes.
“If the ceasefire is violated, we’ll know and we will hold violators accountable through sanctions and other means,” Blinken said, adding, “We facilitated the ceasefire, but it’s the responsibility of the Sudanese Armed Forces and RSF to implement it.”

A remote mechanism, backed by the US, has been established to monitor the truce, Blinken added — a 12-member monitoring committee consisting of three representatives from the warring sides, three from the US, and three from Saudi Arabia.

Sudan descended into chaos after fighting erupted in mid-April between the country's military, led by General Abdel Fattah Burhan, and the paramilitary RSF, commanded by Mohamed Hamdan Dagalo.

The fighting has killed at least 863 civilians, including at least 190 children, and wounded more than 3,530 others, according to the Doctors Syndicate, which tracks civilian casualties. The toll could be much higher, the medical group said. 

The conflict has also turned Khartoum and other urban areas into battlefields. Early on, foreign governments raced to evacuate their diplomats and nationals as thousands of foreign residents scrambled to get out of Sudan.

More than a million Sudanese were forced from their homes by the fighting, including over 840,000 who have sought shelter in safer parts of the country, and another 250,000 who crossed into neighbouring countries, according to the UN figures.
