Sudan yesterday marked two years of a war that has killed tens of thousands, displaced 13 million and triggered the world's worst humanitarian crisis -- with no sign of peace.

Fighting erupted on April 15, 2023 between the regular army, led by Abdel Fattah al-Burhan, and the paramilitary Rapid Support Forces, headed by his former deputy Mohamed Hamdan Daglo.

Khartoum quickly became a battleground. Bodies lined the streets. Hundreds of thousands fled. Those left behind struggled to survive.

"I've lost half my bodyweight," said 52-year-old Abdel Rafi Hussein, who stayed in the capital under RSF control until the army retook it last month. "We're safe (now), but still, we suffer from a lack of water and electricity and most hospitals aren't working."

The army's recapture of Khartoum marked a turnaround after more than a year of setbacks.

Many civilians celebrated what they called the "liberation" of the capital from the RSF, whose fighters were accused of widespread looting and sexual violence.

But now the RSF is seeking to cement its grip on the vast western region of Darfur, where it has launched a deadly assault on El-Fasher -- the last major city in the region outside its control.

More than 400 people have been killed in the offensive, the United Nations said, with the paramilitaries having claimed control of the nearby Zamzam displacement camp on Sunday.

An estimated 400,000 civilians fled the famine-hit camp as the RSF advanced, according to the International Organization for Migration (IOM).

The army said yesterday that it had carried out "successful air strikes" against RSF positions northeast of the city.

In total, the conflict has displaced some 13 million people, 3.8 million of them abroad, according to UN figures.
