Egyptian political groups blame each other for violence outside Brotherhood headquarters

Egypt's powerful Muslim Brotherhood says it holds the opposition and "thugs" responsible for the most violent clashes yet outside the Islamist group's headquarters in Cairo.

Meanwhile liberal opposition groups say the president, who hails from the Islamist group, is responsible because his government has failed to stabilize Egypt.

Fighting between opponents and supporters of the Brotherhood on Friday wounded around 175 people. The Brotherhood says six of its offices across the country were also attacked.

Muslim Brotherhood secretary-general Mahmoud Hussein told journalists Saturday that some media are falsely portraying what took place as a fight. He says what happened near the group's headquarters was an attack on Brotherhood members by "thugs."

Opposition leader Mohamed ElBaradei says the violence is due to the regime's failure to address root causes of anger.
