Several detainees in Libya have died after being tortured in recent weeks , the human rights group Amnesty International said Thursday . The humanitarian aid group Doctors Without Borders said it was halting its work in detention centers in Misrata because detainees are `` tortured and denied urgent medical care . '' The agency , known by its French acronym MSF , said it has treated 115 people with torture-related wounds from interrogation sessions . Christopher Stokes , general director of MSF , told CNN that two detainees died -- one in October and another in November -- within 30 minutes of being interrogated . Autopsies were not carried out , so the cause of death is unknown , he said . In a statement , Amnesty described `` widespread torture and ill-treatment of suspected pro-Gadhafi fighters and loyalists , '' a reference to those who fought for the regime of leader Moammar Gadhafi until his ouster and death . `` Amnesty International delegates in Libya have met detainees being held in and around Tripoli , Misrata and Gharyan , who showed visible marks indicating torture inflicted in recent days and weeks . Their injuries included open wounds on the head , limbs , back and other parts of the body . `` The torture is being carried out by officially recognized military and security entities as well by a multitude of armed militias operating outside any legal framework , '' Amnesty said in a statement . Libyan officials could not be immediately reached for comment . Interim Prime Minister Abderrahim el-Keib , in a televised addressed Wednesday evening about the state of affairs in Libya , said a plan was in progress to take over prisons partially . Libya 's ambassador to the United Nations , Mohammed Shalgham , told the United Nations on Wednesday that Libya does not approve of any abuse of detainees and was working to stop any such practices . Amnesty published what it said were quotes from tortured detainees in Misrata . `` Five men in plain clothes took turns beating and whipping me . ... They suspended me from the top of the door by my wrists for about an hour and kept beating me . They also kicked me , '' one said , according to the human rights group . `` Yesterday they beat me with electric cable while my hands were cuffed behind my back and my feet were bound together . They threatened to send me back to the militia who captured me , who would kill me , '' said another , according to Amnesty . MSF said some of the patients its personnel have treated were tortured again after being returned to detention centers . `` Some officials have sought to exploit and obstruct MSF 's medical work , '' said Stokes , the general director . `` Patients were brought to us for medical care between interrogation sessions , so that they would be fit for further interrogation . This is unacceptable . Our role is to provide medical care to war casualties and sick detainees , not to repeatedly treat the same patients between torture sessions . '' MSF officials told CNN the injuries included cigarette burns , fractures , and electroshocks , which are `` definitely '' due to torture . There were also clear signs of beatings , Stokes said . The detainees with torture wounds includes former fighters in the conflict , `` but also people who have been accused of theft , '' Stokes said . MSF is continuing its work providing mental health services in Misrata schools and health centers , he said . Libya faces challenges in building a new nation . Navi Pillay , the U.N. High Commissioner for Human Rights , voiced similar concerns about torture in Libya , sparking the response from Shalgham , Libya 's U.N. envoy . Pillay said the International Committee of the Red Cross had visited more than 8,500 detainees in about 60 places in Libya between March and December . The majority of the detainees are accused of being Gadhafi loyalists , Pillay said Wednesday . She said the issue is part of the difficulties Libya is having in law enforcement and security as the country transitions from Gadhafi 's rule . `` The lack of oversight by the central authorities creates an environment conducive to torture and ill-treatment , '' Pillay said .
