Sinai borderLast 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.

Israel, Hamas, and Egypt have aligned their strategies and formed an unlikely alliance against the Islamic State in Sinai, who are planning increasingly sophisticated and daring attacks in the region, The Washington Post reported on Sunday.

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 Russian charter 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.

“They have genius strategists,” said Mohannad Sabry, an Egyptian journalist and author of a book on Islamist insurgency in the Sinai. “If you study the map of their attacks, they obviously know what they are doing exactly, and it shows that they have a great deal of freedom of mobility."
