Is Gitmo closing or just moving to Afghanistan?

A friend just e-mailed me an article that Gitmo was closing. Is it? Or just moving to another place?

While in Afghanistan with Global Exchange, I visited a lot of NGOs. At one human rights NGO, someone mentioned that the U.S. was building a prison outside of Kabul that would hold Afghan Guantanamo prisoners. According to them it's being administered by the Justice Sector Support Program of the State Department.
