Prosecutors will investigate allegations that Egypt’s ousted president escaped from prison during the 2011 revolution with help from the Palestinian militant group Hamas.

Egytian prosecutors have ordered the arrest of the leader of Muslim Brotherhood and his deputy for the killing of eight protesters in clashes outside the group’s Cairo headquarters.

The armed forces ousted Egypt’s first democratically elected president today after just a year in power, installing a temporary civilian government, suspending the constitution and calling for new elections.
