Mygoma’s dead babies are among the invisible victims of the war in Sudan, Africa’s third-largest country by area.

More than 300,000 people have crossed Sudan's borders since the fighting erupted, with the largest numbers heading north to Egypt from Khartoum or west to Chad from Darfur.

The sound of clashes and artillery fire could be heard in Bahri, one of the three cities around the confluence of the Blue Nile and White Nile rivers that make up Sudan's greater capital.

The agreement commits both sides in general terms to let in badly needed humanitarian assistance after looting and attacks targeting aid in the impoverished country, Africa's third largest in area.

Almost a month of heavy fighting has turned Khartoum into a war zone, with the city's five million residents enduring artillery barrages, gunfights, air strikes and anti-aircraft fire.

The fighting in Khartoum, which erupted April 15, has prompted hundreds of thousands of people to flee their homes and triggered an aid crisis.

Multiple truce deals have been declared, without effect, since fighting erupted between army and paramilitary forces on April 15 in the poverty-stricken country with a history of political instability.

The sudden collapse into warfare has killed hundreds, triggered a humanitarian disaster, sent an exodus of refugees to neighbouring states and risks dragging in outside powers, further destabilising the region.

At least 512 people have been killed and 4,193 wounded in the fighting, according to health ministry figures, although the real death toll is likely to be much higher.

The fighting has killed hundreds of people and left some neighbourhoods of greater Khartoum in ruins, prompting thousands of foreigners and Sudanese to flee.

The fighting has pitted forces loyal to army chief Abdel Fattah al-Burhan against those of his former deputy Mohamed Hamdan Daglo, who commands the RSF.

Ultimately, the White House report suggested, the long-term failure of the war, including the Taliban's surprising resilience and the weakness of government forces, meant the ending was never going to go well.
