CAIRO, Sept 11 (Aswat Masriya) - Tens of prisoners in the Portsaid general prison sustained superficial injuries after a fight broke out between pro-Muslim Brotherhood inmates and a number of criminal prisoners on Thursday.

The altercation took place during the prisoners' prescribed exercise period, quickly escalating into a fight, the Ministry of interior (MOI) said in a statement on its official Facebook page.

The guards were able to break up the fight and control the situation, moving the prisoners back to their cells, the statement added.
