The government’s move gives authorities the power to charge any member of deposed president Mohamed Morsi’s movement with belonging to a terrorist group, as well as anyone who finances the group or promotes it “verbally or in writing.”
The Brotherhood, which was founded in 1928, was Egypt’s best-organized political force until this summer’s crackdown. It estimates its membership at up to 1 million people.
The government decision is the latest step in a crackdown that has put thousands of Brotherhood supporters in jail, including most of the group’s top leadership.
Hundreds of Morsi supporters have been killed in the crackdown by security forces, and the group has already been banned by a court that ordered its assets to be seized.
Since Morsi’s downfall, at least 350 members of the security forces have been killed in bombings and shootings.
