The man is the first foreigner to be abducted and threatened with death by militants in Egypt since an Islamist insurgency erupted two years ago.
In a video posted online by the militants, the Croatian identifies himself as Tomislav Salopek working for French company CGG, and appears kneeling at the feet of a hooded man holding a knife.
Reading from a sheet of paper, he says he will be executed within 48 hours if Egypt’s government fails to release Muslim women held in prisons.
Salopek, wearing an orange jumpsuit, did not say when the countdown began.
He said he was abducted on July 22 by the Sinai Province group, ISIS' Egyptian affiliate based in the Sinai Peninsula.
Formerly known as Ansar Beit al-Maqdis, the group changed its name when it pledged allegiance to ISIS in November. » | Wednesday, August 5, 2015
