The U.S. military says Afghanistan's government has ordered the release of 37 "dangerous" prisoners who it believes pose threats to the country and the region.

The release of prisoners has been a sticking point in Afghan-U.S. relations as the two sides struggle over a deal allowing U.S. and allied troops to remain in the country past the end of this year.

The U.S. on Monday condemned the move to release of "dangerous insurgents who have Afghan blood on their hands," linking them to roadside bombings and attacks on foreign and government troops.

Afghan officials did not return repeated calls for comment Monday."
