Egypt's East Cairo prosecution has ordered the detention of Muslim Brotherhood leading figures Khairat El-Shater and Saad El-Katatni for 15 days pending investigations into charges of inciting murders.
Brotherhood deputy leader El-Shater and El-Katatni, head of the group's Freedom and Justice Party (FJP), were arrested and detained, along with many other Islamist figures, following the 3 July ouster of President Mohamed Morsi, who hails from the Brotherhood.
The duo are officially accused of inciting violence and "paying money to thugs to assault protesters last December at the presidential palace", when Morsi was still in power.
The infamous incident marked the beginning of clashes between supporters and opponents of Morsi. It resulted in at least ten deaths.
