The jihadists had issued a 48 hour deadline that ran out on August 7 threatening to kill the employee of a French firm if Muslim women prisoners were not released from Egyptian jails.
According to a Syrian NGO, the jihadists have executed more than 3,000 people, including 1,800 civilians, in Iraq and Syria, where they declared an Islamic caliphate in June 2014 in territory under their control.
In February, jihadists in Libya linked to IS claimed the execution of 21 Coptic Christians, all but one of them Egyptians, and in April the execution of 28 Christians, all Ethiopians.
