Advocacy organization Amnesty International says that South Sudan's National Security Service is still holding 33 people in inhumane conditions in their headquarters in Juba.

Amnesty's campaigner Nyagoah Tut wrote to supporters telling them that the 33 detainees have been denied the right to be brought promptly before a judge and the right to challenge the lawfulness of their detention.

“Some detainees are being held incommunicado, without any access to family members or the outside,” said the organization.

Detainees are fed a monotonous diet, and sometimes only eat once a day. They sleep on the floor and do not have access to adequate medical care.

Amnesty also claims that some have been beaten, especially during interrogation or as a form of punishment. “These poor conditions amount to ill-treatment and may also amount to torture in some cases,” Amnesty said.
