Islamist figure Magdi Hussein stopped at Cairo airport before flight to Turkey

Authorities at Cairo International Airport on Friday prevented head of the Islamist Labor Party Magdi Hussein from leaving Egypt on a flight to Turkey, Al-Ahram's Arabic news website reported.  

Hussein, a staunch supporter of ousted president Mohamed Morsi, is also a leading figure in the Muslim Brotherhood-led National Alliance to Support Legitimacy (NASL).

The Islamist figure was also an outspoken critic of autocratic president Hosni Mubarak, under whom he served a two-year prison sentence for entering Gaza illegally through a cross-border tunnel.

Security forces have cracked down on the Brotherhood and their Islamist allies since Morsi's ouster. Thousands have been imprisoned and hundreds killed in clashes with security forces.
