UN chief Antonio Guterres has warned that the Sudanese war could cause far-reaching regional instability.
The UN chief has urged rival Sudanese forces "to silence the guns and raise the volume for peace."
Antonio Guterres noted at a Security Council meeting concerning Sudan that next month will mark one year since the conflict between the army and the paramilitary Rapid Support Forces (RSF) led to thousands of killings, displacement and shortage of food and other essentials.
The "conflict has taken a devastating toll on the people of Sudan," he said.
"There is now a serious risk that the conflict could ignite regional instability of dramatic proportions, from the Sahel to the Horn of Africa and the Red Sea."
Humanitarian crisis
He said everyone in Sudan should "honour the values of Ramadan by honouring a Ramadan cessation of hostilities" and that it "must lead to a definitive silencing of the guns across the country, and set out a firm path towards lasting peace for the Sudanese people."
Ramadan, the holiest month in the Islamic calendar, is scheduled to begin Sunday.
The UN chief stressed that the "humanitarian crisis in Sudan is reaching colossal proportions," and at least 25 million people need life-saving aid.
"Over 14,000 people have been killed, although that number is likely far higher," he said, adding that 6.3 million have been internally displaced since the beginning of the conflict.
Food insecurity
"Another 1.7 million people have fled to neighbouring countries," he said.
Guterres said infrastructure in Sudan is destroyed and basic services are halted with more than 70% of health facilities in conflict-affected areas not functional.
With millions of children out of school, Guterres stressed "water and sanitation systems are breaking down. Diseases are multiplying. Hunger is stalking Sudan. Some 18 million people are acutely food insecure."
Urging authorities to implement the Jeddah Declaration, Guterres encouraged officials "to continue efforts to facilitate humanitarian access, including across conflict lines."
Failed ceasefire efforts
"The Jeddah platform constitutes a critical and promising forum for dialogue – and African participation remains indispensable," he added.
Sudan has been marred by fighting between the army, led by General Abdel Fattah al-Burhan, who is the head of the ruling Sovereign Council, and the RSF.
At least 33,000 people have been injured in the conflict that started last April, according to UN figures.
Several ceasefire agreements brokered by Saudi Arabia and US mediators have failed to end the violence.
