President Abdel Fattah al-Sisi  has once again threatened to crush the militants.
âThe armed forces and the police will avenge our martyrs and restore security and stability with the utmost force in the coming period â  he  said after Fridayâs carnage.
 Sisi  has called for a comprehensive campaign to counter what  he  describes as the existential threat of radical jihadism  deploying moderate clerics to promote moderate Islam  for instance.
 He  is expected to run for a second term early next year. Even with a convincing win   he  will face pressure to deliver on promises of stability  especially if attacks like that on  Al Rawdah  persist.
In a December 2016 issue of al-Nabaa  one of the groupâs religious leaders left little doubt that Sufis would be targeted. It mentioned  Al Rawdah  directly.

The flying taxi developed by German drone firm Volocopter  resembles a small  two-seater helicopter cabin topped by a wide hoop studded with 18 propellers.
 It  was unmanned for  its  maiden test run in a ceremony arranged for Dubai Crown Prince Sheikh Hamdan bin Mohammed.
 Volocopter  is in a race with more than a dozen well-funded European and U.S. firms  each with  its  own science fiction-inspired vision for creating a new form of urban transport that is a cross between a driverless electric car and a short-haul  vertical takeoff-and-landing aircraft.
“Implementation would see you using your smartphone  having an app  and ordering  a Volocopter  to the next voloport near you.  The volocopter  would come and autonomously pick you up and take you to your destination ” CEO Florian Reuter said.
