Sadrist reorganization to be explained during prayers

BAGHDAD, Iraq (CNN) - The reorganization of Shiite cleric Muqtada al-Sadr's notorious Mehdi Army militia will be spelled out on Friday during weekly prayers at mosques affiliated with the movement, a Sadrist official told CNN on Thursday.

The militia will be reorganized largely into a cultural movement called the Momahidoun and elite military cells dedicated to "armed resistance against the occupiers," according to Sheikh Salah al-Obadiah.

The announcement will reinforce and elaborate on a initial statement issued in June about the development.
