The current chaos in Cairo is being watched with concern in Libya and Tunisia.
Both of these nations were transformed by the Arab Spring.
There's a saying in the Middle East, as goes Egypt so goes the Arab World.
The BBC's North Africa correspondent, Rana Jawad, says some Libyans and Tunisians are pleased that Egypt's president Norsi has gone, since they are also fighting the Islamization of politics.
However, she adds that the disregard for the law, with the military intervention, could bring instability and breed militancy.
