The women at the community kitchen in the besieged Sudanese city of el-Fasher are sitting in huddles of desperation.

"Our children are dying before our eyes," one of them tells the BBC.

"We don't know what to do. They are innocent. They have nothing to do with the army or [its paramilitary rival] the Rapid Support Forces. Our suffering is worse than what you can imagine."

Food is so scarce in el-Fasher that prices have soared to the point where money that used to cover a week's worth of meals can now buy only one. International aid organisations have condemned the "calculated use of starvation as a weapon of war".

The hunger crisis is compounded by a surge of cholera sweeping through the squalid camps of those displaced by the fighting.

The medical charity Doctors Without Borders (MSF) on Thursday said Sudan is experiencing the worst cholera outbreak the country has seen in years, fuelled by the ongoing civil war. There have been nearly 100,000 cases and 2,470 deaths over the past year, it said, with the current epicentre near el-Fasher.

The BBC has obtained rare footage of people still trapped in the city, sent to us by a local activist and filmed by a freelance cameraman.

The Sudanese army has been battling the Rapid Support Forces (RSF) for more than two years after their commanders jointly staged a coup, and then fell out.

El-Fasher, in the western Darfur region, is one of the most brutal frontlines in the conflict.

The paramilitaries tightened their 14-month blockade after losing control of the capital Khartoum earlier this year, and stepped up their battle for el-Fasher, the last foothold of the armed forces in Darfur. The fighting escalated this week into one of the most intense RSF attacks on the city yet.

In the north and centre of the country where the army has wrestled back territory from the RSF, food and medical aid have begun to make a dent in civilian suffering.

But the situation is desperate in the conflict zones of western and southern Sudan.

At the Matbakh-al-Khair communal kitchen in el-Fasher late last month, volunteers turned ambaz into a porridge. This is the residue of peanuts after the oil has been extracted, normally fed to animals.

Sometimes it is possible to find sorghum or millet but on the day of filming, the kitchen manager says: "There is no flour or bread."........
