Fierce clashes between anti-Muslim Brotherhood protesters and members of the Islamist group have erupted in Saea Square in the Nile Delta city of Damanhour, less than a day after bloody confrontations left 26 injured.
The two sides hurled rocks at one at one another amid complete absence of security forces.
Some 1,500 members of the Muslim Brotherhood had organised a rally at the groups headquarters in Saea Square in support of President Mohamed Morsi's controversial Constitutional Declaration.
Anti-Brotherhood protesters reportedly attacked the Brotherhood demonstration with Molotov cocktails and rocks. The Islamist group responded with truncheons.
Damanhour is widely regarded to be a Brotherhood stronghold. A number of attacks on Muslim Brotherhood headquarters have taken place across the country since the declaration was announced on Thursday.
