Former Dubai police chief, Dahi Khalfan said Sunday on Twitter that terrorist groups will be perished if they continue to dream about the establishing of an Islamic State (IS) caliphate in Sinai, Al Bawaba News reported. Khalfan added that all channels that support IS are hated in the Arab world. Since September 2013, the Egyptian army has been carrying out an ongoing military campaign against IS-loyal group Wilayat Sinai, formerly known as Ansar Bayt Al Maqdis, after it claimed responsibility for several deadly attacks targeting Egyptian military and police personnel.
