CAIRO—An online image circulated Wednesday purported to show the beheading of a Croatian hostage held by the ISIS group’s Egyptian affiliate, the first such killing of a foreign captive in Egypt since the extremists set up a branch here.
The killing of the 30-year-old oil and gas sector surveyor likely will rattle companies with expatriate workers in Egypt and cast a cloud over President Abdel-Fattah el-Sissi’s attempts to boost international investment to revive the economy, battered by years of turmoil.
