Egypt's top prosecutor referred 64 people described as members of the Muslim Brotherhood to military prosecutors on Saturday for involvement in an alleged military wing, linked with the Brotherhood.
An investigation showed that the Brotherhood leaders have created teams, which include armed members to make up a military wing with the purpose of targeting judges, security personnel and facilities, a statement from Prosecutor General Hisham Barakat's office said.
The teams operated in Cairo, Alexandria and Port Said.
According to the statement, 23 of the defendants have confessed to membership in the armed group, arms possession and manufacture and 19 confessed to carrying out different acts of vandalism.
Egypt's President Abdel Fattah al-Sisi issued in October 2014 a new law which expands the jurisdiction of military tribunals on civilians, allowing the referral of crimes committed against the state's public and "vital" facilities to the military judiciary.
The Brotherhood has faced a crackdown since the July 2013 ouster of former president Mohamed Mursri, with the majority of the group's leaders sitting behind bars where they either serve time or await trial.
Today, Brotherhood Supreme Guide Mohamed Badie was served a life sentence by a Cairo court for managing an "operations room" following the dispersal of the two pro-Mursi camps in August 2013.
Egypt listed the Brotherhood as a terrorist organisation in December 2013 and insists it is behind the stringent wave of militancy which has targeted security personnel since Mursi's ouster.
The Brotherhood continuously denies the accusations.
