The trial of top Muslim Brotherhood leaders charged with inciting deadly violence against anti-Islamist protesters opened in Egypt on Wednesday, dpa reported.
The 30 defendants include Brotherhood chief Mohammed Badie and his two deputies, Khayrat al-Shater and Mohammed Bayoumi.
They are charged with inciting attacks on opponents in June in Cairo that left nine people dead and 91 wounded.
At the start of the trial, the defendants chanted slogans against the military, which deposed president Mohammed Morsi of the Brotherhood in July, reported state-run newspaper al-Ahram.
"Down with the military's rule. We are in a state, not in a camp," they shouted inside the defendants' cage at a makeshift courtroom in a police building in southern Cairo.
The trial comes two days after a court began hearing another case involving 14 Islamists, including Badie, charged with incitement to murder opponents.
Hundreds were killed in a military-backed crackdown on supporters of Morsi, Egypt's first democratically elected president.
