The Washington Post calls yesterday's developments "a stunning turnaround for the decades-old Islamist organization, which rose to the height of political power in 2012 with the election of Mohamed Morsi — a former Brotherhood leader — as president in Egypt’s first open democratic election."
UPDATE: AP reports that on Thursday, the government arrested a number of Muslim Brotherhood members, froze the assets of 1,000 charities and NGO's linked to the Brotherhood, placed 100 Brotherhood schools under government supervision and warned that holding a leadership post in the Muslim Brotherhood could be grounds for the death penalty.
UPDATE 2: The New York Times (Dec. 26) reports:
After widespread confusion and concern about the funds cutoff, in particular, government officials partly reversed course on Thursday night, saying that the organizations whose funds had been frozen — more than a thousand of them — would be allowed access to money to continue operating.
