Egypt has charged ousted president Mohamed Morsi with leaking national security secrets to Qatar - yet another crackdown on him and his banned Muslim Brotherhood.
The nation's top prosecutor says Morsi and 10 co-defendants will go on trial for providing Qatari intelligence with sensitive documents during his year in office. A senior executive for the Qatar-owned al-Jazeera television network is among those charged.
Saturday's statement says the case represents the largest act of treason the Muslim Brotherhood has carried out against the nation.
The prosecutor says the leaked documents included details about the Egyptian army and its weapons.
Morsi is already in jail facing three additional trials and could be sentenced to death. He has been imprisoned since his ouster in July of last year by then-army chief Abdel Fattah el-Sissi, who was elected president earlier this year.
On Saturday, President Sissi urged Egyptians to be patient following a massive power outage. Thursday's hours-long power outage blacked out most of Cairo.
Power outages were a factor that contributed to protests last year demanding Morsi's ouster.
Three years of political unrest in Egypt, starting with the 2011 uprising that toppled longtime president Hosni Mubarak, have wreaked havoc on the country's economy.
