The wide-ranging and concentrated attacks that targeted Egyptian military targets in Sinai on Friday signaled a dangerous event. This stunning attack by militants in Sinai comes only four months after the October attack that killed 31 soldiers and injured several others. If small and organized militias could target a series of strategic military sites in Arish in North Sinai despite the exceptional security measures, then will it be far-fetched to expect these groups to control the city in the near future and declare an Islamic emirate there? And if the attacks on Sinai are to cause aftershocks in Egypt, Gaza, too, will not be spared the implications.
