According to former detainees, the underground prison, which is staffed by Somali guards, consists of a long corridor lined with filthy small cells infested with bedbugs and mosquitoes. One said that when he arrived in February, he saw two white men wearing military boots, combat trousers, gray tucked-in shirts and black sunglasses. The former prisoners described the cells as windowless and the air thick, moist and disgusting. Prisoners, they said, are not allowed outside. Many have developed rashes and scratch themselves incessantly. Some have been detained for a year or more. According to one former prisoner, inmates who had been there for long periods would pace around constantly, while others leaned against walls rocking.
A Somali who was arrested in Mogadishu and taken to the prison told The Nation that he was held in a windowless underground cell. Among the prisoners he met during his time there was a man who held a Western passport (he declined to identify the mans nationality). Some of the prisoners told him they were picked up in Nairobi and rendered on small aircraft to Mogadishu, where they were handed over to Somali intelligence agents. Once in custody, according to the senior Somali intelligence official and former prisoners, some detainees are freely interrogated by US and French agents. Our goal is to please our partners, so we get more [out] of them, like any relationship, said the Somali intelligence official in describing the policy of allowing foreign agents, including from the CIA, to interrogate prisoners. The Americans, according to the Somali official, operate unilaterally in the country, while the French agents are embedded within the African Union force known as AMISOM.
Since the Bush-era torture protocols have not been officially rescinded, it's reasonable to think that torture is still occurring at these sites.
