The Muslim Brotherhood could cease to exist when this is over with, at the very least it will be a hollowed out shell of what it once was.

CAIRO (AP) — Egyptian authorities on Wednesday continued their crackdown on the Muslim Brotherhood and its allies by arresting two more high-profile Islamist figures, while officials said that they had started a closed hearing in a prison outside Cairo on whether to release jailed ex-president Hosni Mubarak.

The arrested Islamists include a preacher known for his fiery sermons who was reportedly caught as he tried to flee to neighboring Libya in disguise, and a spokesman for the Brotherhood said to be on his way to catch a flight out of the country.

They are the latest allies of President Mohammed Morsi, who hails from the Brotherhood, to be arrested. On Tuesday authorities detained the Brotherhood’s supreme leader and spiritual guide, Mohammed Badie, dealing a serious blow to an embattled movement now struggling to keep up its protest campaign against the military’s overthrow of Morsi and subsequent deadly assaults on pro-Morsi sit-ins.
