The Obama administration has released the names of 46 prisoners at its detention center at Guantanamo Bay in Cuba whom it wants to hold indefinitely.
The men are considered too dangerous to release, but the United States lacks the evidence to prosecute them.
Pentagon spokesman Todd Breasseale says they are held under the Authorized Use of Military Force act authorized by Congress in 2001.
The Defense Department released the names on June 17 after the "Miami Herald" sued for its release in a U.S. District Court in Washington.
The names of Guantanamo prisoners have long been public.
But the government had not identified those it designated in 2010 as too dangerous to release even if Guantanamo closed.
