Abdulqadir Abdullah Ali suffered serious nerve damage to his leg during the long siege of the Sudanese city of el-Fasher because he could not get medicine for his diabetes.

The 62-year-old walks with a heavy limp, but he was so panicked when fighters from the paramilitary Rapid Support Forces (RSF) finally captured the city in the western Darfur region, he felt no pain as he ran.

"The morning the RSF came there were bullets, many bullets, and explosives going off," he says.

"People were out of control [with fear], they ran out of their houses, and everyone ran in different directions, the father, the son, the daughter - running."

The fall of el-Fasher after an 18-month siege is a particularly brutal chapter in Sudan's civil war.
