The Financial Times is reporting the US government is planning the construction of a high-security prison in Afghanistan to hold detainees. The planned site for the jail is Pol-e-Charki, a rundown prison near Kabul that dates back to the Soviet era. The jail would be phased in as an alternative to the US military prison at Guatanamo Bay, Cuba, where the US is currently holding more than 500 people. Another 500 prisoners are under US detention at military facilities and secret locations across Afghanistan.
