The Associated Press reports: An Afghan investigative commission accused the American military Saturday of abusing detainees at its main prison in the country, saying anyone held without evidence should be freed and backing President Hamid Karzai’s demand that the U.S. turn over all prisoners to Afghan custody.

The demands put the U.S. and the Afghan governments on a collision course as negotiations continue for a Strategic Partnership Document with America that will determine the U.S. role in Afghanistan after 2014, when most foreign troops are due to withdraw. By pushing the detainees issue now, Karzai may be seeking to bolster his hand in the negotiations.

At the center of the dispute are hundreds of suspected Taliban and al-Qaida operators captured by American forces. The controversy mirrors that surrounding the U.S. detention center at Guantanamo Bay. There, as at the prison in Afghanistan, American forces are holding many detainees without charging them with a specific crime or presenting evidence in a civilian court.
