But spokesman Colonel Ahmed Aly warned against anyone approaching military facilities or threatening national security, in remarks at a news conference after at least 42 people were killed in violence outside the Republican Guard headquarters in Cairo.

This is while Egyptian military officials said supporters of ousted Morsi have seized two army soldiers in the capital, Cairo.

State news agency MENA quoted the officials as saying that armed supporters of Morsi put the Egyptian soldiers, identified as Samir Abdallah Ali and Azzam Hazem Ali, in a car on Monday and forced them “to make pro-Morsi and anti-army statements on a loudspeaker.”

Dozens of Morsi supporters were killed and hundreds more wounded in an attack on a sit-in outside the Republican Guard headquarters in the capital on Monday.

Muslim Brotherhood says over 50 people, including five children, died in the attack.

Meanwhile, Egypt’s judicial authorities have ordered the closure of Muslim Brotherhood headquarters in Cairo after security forces allegedly found arms inside the building.

Police found “flammable liquid, knives and arms to be used against the June 30 protests,” an Egyptian security official said on condition of anonymity.

Muslim Brotherhood political arm, the Freedom and Justice Party, has called for “an uprising by the great people of Egypt against those trying to steal their revolution with tanks.”
