KABUL (AFP) - Afghanistan said on Monday that it expects to release within two weeks a first batch of alleged Taleban prisoners whom the United States says are responsible for dozens of NATO and Afghan deaths.

Kabul announced on Jan 9 that a total of 72 detainees held at Bagram jail near Kabul would be freed due to lack of evidence, and an official said on Monday that 37 were to be released initially.

The US military force in Afghanistan condemned the news of the releases, saying the prisoners were "dangerous insurgents" who had "Afghan blood on their hands".

"The ARB (Afghan Review Board) is releasing back to society dangerous insurgents who have Afghan blood on their hands," the US military in Afghanistan said in a statement.

It said 17 of those about to be freed were linked to improvised explosive device attacks, the deadliest of the Taleban's weapons, while others were connected to the deaths or wounding of 11 Afghan and 42 US or coalition soldiers.

The issue threatens further to strain US-Afghan relations, amid pressure for the two countries to sign a long-delayed security deal allowing some American soldiers to stay in the country after 2014.

Mr Abdul Shukur Dadras from the government body reviewing detainees at Bagram, which was previously run by US forces, said 37 prisoners would be released soon.

"Their dossiers are reviewed, completed and we have ordered their release," he told AFP.

"They will be released from the prison after the required technical and security procedures are completed. This will, I think, take more than one week and less than two weeks."

Mr Dadras also said the review of the remaining prisoners was continuing.

Amid resurgent Taleban violence, US-Afghan relations are strained over a number of issues including President Hamid Karzai's refusal to sign a pact governing Washington's future military role in Afghanistan.

Bagram was the main detention centre housing Taleban and other insurgents captured by the Western military forces until it was transferred to Afghan control last year.

After taking control of the facility, Mr Karzai appointed the ARB to investigate and reassess the detainees there.

On Saturday, Mr Karzai said Bagram, while under US administration, was "a Taleban-making factory" - indicating it turned Afghans against their government.
