Many at Guantanamo had low-level or no terrorism ties

The militants crept up behind Mohammed Akhtiar as he squatted at the spigot to wash his hands before evening prayers at the Guantanamo Bay detention camp.

They shouted "Allahu Akbar" — God is great — as one of them hefted a metal mop squeezer into the air, slammed it into Akhtiar's head and sent thick streams of blood running down his face.

American troops dragged Akhtiar out of his home in Gardez, Afghanistan, in May 2003, flew him to Guantanamo in shackles that July and held him there for more than three years. . . .

An eight-month McClatchy investigation in 11 countries on three continents has found that Akhtiar was one of dozens and perhaps hundreds of men whom the U.S. has wrongfully imprisoned in Afghanistan, Cuba and elsewhere on the basis of flimsy or fabricated evidence, old personal scores or bounty payments.
