But the issue of detainees is more immediate.
Transfers were halted in October, when the U.N. shared its preliminary findings with the military coalition.
"We have only stopped transferring some detainees to certain Afghan facilities," said Jamie Graybeal, a spokesman for the international military alliance in Kabul. "The Afghan government has stated its commitment to upholding its human rights obligations and we remain committed to working together with the International Community to support them in their efforts to tackle this difficult problem. "
Issued last month, the U.N. report said Afghan authorities are still torturing prisoners despite promises of reforms. The country's intelligence service earlier had denied any torture in its detention facilities.
The U.N. report said more than half of the 635 detainees it had interviewed were tortured — about the same ratio found in its first report in 2011. It cited brutal tactics including hanging detainees from the ceiling by their wrists, beating them with cables and administering electric shocks.
Many rights activists have expressed concern that such abuses could become more common as international forces draw down and the country's Western allies become less watchful over a government that so far has taken few concrete actions to reform the system.
Abdul Qadir Adalatkhwa, head of the Afghan commission, told reporters that torture and beatings occur in the first stages of the arrest "but not while they are in prison."
"There is no systematic torture in Afghan detention centers," he said. "We didn't identify any private prisons during our investigation."
The Afghan panel also denied an allegation in the U.N. report that the Afghan government appeared to be trying to conceal the mistreatment by hiding detainees in secret locations during inspections by international observers.
