Haunting accounts of torture in newly found detention centre lead to calls for an investigation into what experts say could be among the worst atrocities of Sudan’s civil war

• Evidence of torture found as detention centre and mass grave discovered outside Khartoum

Lying between the makeshift graves is a mattress, a large bloodstain visible in the midday sun. A name is scrawled in Arabic on its ragged fabric: Mohammed Adam.

Who was Adam? Had he ended up here, in a bleak corner of a remote military installation in Sudan’s Khartoum state? Had his body been stretchered on the mattress from the detention centre nearby and dumped into one of hundreds of unmarked graves?
