An Egyptian judicial official says the country's prosecutor general is investigating two Muslim Brotherhood leaders on allegations that they instigated violence against protesters critical of the country's new president, who hails from the Islamist movement.
The Monday decision to question Mohammed el-Beltagy and Essam el-Erian follows clashes Friday between supporters and critics of President Mohammed Morsi that injured more than 100 people.
The investigation comes on the heels of a showdown between Morsi and the prosecutor general. Morsi tried to remove the prosecutor from office, but backed down after pressure from judges.
A security official said three others including a minor suspected of burning empty Brotherhood buses at the protest were ordered detained pending investigation. Both officials spoke anonymously as they were not allowed to talk to reporters.
