Afghan President Hamid Karzai on Monday took a swipe at the United States for not doing enough to transfer all prisoners currently in US custody to the Afghan authorities, dpa reported.
He also accused US forces of continuing to capture Afghans.
The US officially handed over the control of the major military prison at Bagram airbase, also known as Parwan Detention Centre, to Afghan forces in September.
At a court hearing Sunday, the Afghan attorney general and the military police commander presented reports that said "even prisoners who were presumed innocent by the court are still being held," Karzai's office said.
"In addition, there are people who, against the provisions of the MoU (Memorandum of Understanding) already signed, are newly imprisoned by the American forces," it said.
Karzai ordered his administration "to take all required and urgent measures to ensure a full Afghanization of prison affairs and a complete transfer of its authority," his office said.
Karzai's spokesman Aimal Faizi said the US President Barack Obama before his election had given word to the Afghan president that he would solve the issue within two months.
Karzai and Obama held a video conference ahead of the US presidential election, in which "Obama asked for a two-month moratorium because of his business in the election campaign. The moratorium is over, and besides that, there is no administrative detention in Afghan legal laws," Faizi told reporters.
The US had insisted that a number of prisoners considered as security threats should remain in their custody for an unknown term, despite having no evidence against them, according to Faizi.
"We want to discuss further with the US authorities to solve this problem soon, considering the Afghan legal laws."
Bagram prison holds more than 3,000 suspected insurgents. The two countries signed the detainee transfer pact in March.
More than 30 inmates of different nationalities, including Afghans, remain in the custody of US forces pending clarification of some elements of the handover agreement, according to officials.
But Faizi said more than 70 Afghan inmates, who have been presumed innocent by the court, are still in the US custody.
