The Questions now: What about the other 48 detainees? were they already been executed?
Sudan has freed 57 prisoners from a key Darfur rebel group, the Justice and Equality Movement (Jem), officials say.
President Omar al-Bashir announced the releases during a speech in Darfur's capital El Fasher, and declared: "The war is over."
The releases are part of a ceasefire deal signed on Tuesday by Mr Bashir and Jem leaders - formerly bitter enemies.
The deal raises hopes of an end to years of conflict in Darfur, however some rebel factions have not signed up.
Jem's leader, Khalil Ibrahim, hailed the deal as "a very important step".
