The Islamic State of Iraq and al-Sham (ISIS) has officially entered Egypt. On November 10, Ansar Beit al-Maqdis, a militant movement that operates out of the northern Sinai Peninsula, pledged allegiance to ISIS and its leader, Abu Bakr al-Baghdadi. The group, which emerged after the 2011 uprising that overthrew Egyptian President Hosni Mubarak, has already established itself as a formidable player in its own right. In recent months, it has staged devastating attacks on Egypt’s police forces and claimedresponsibility for a series of suicide attacks on military facilities in Cairo and the Sinai Peninsula.
