The Jerusalem Post:
Islamic State’s Egyptian affiliate, referred to as Wilayat Sinai, is well equipped with weaponry and has been plotting more sophisticated attacks since taking responsibility for the October bombing of a Russiancharter plane which killed all 224 passengers aboard.
Additionally, the group consistently carried out attacks against Egyptian soldiers, bombarding military outposts and planting roadside bombs in the vicinity.
Last week, Hamas deployed several hundred fighters along the Gaza-Sinai border together with Egypt to prevent ISIS fighters in the region from breaching the coastal enclave.
