The move occurred as Egypt is suffering series of bloody attacks from the Islamic State group, aiming at the security force on Sinai Peninsula. Israel temporarily closed the Nitzana border crossing into Sinai to assure safety.

The Islamic State's affiliate in Egypt, 'Sinai Province', confirmed it had fired three Grad rockets at Israel, adding that it was in retaliation for Israel supporting Egypt's armed forces on Wednesday when the jihadis attacked army checkpoints in northern Sinai.
