They were instructed to carry out smaller missions on behalf the Islamic State, also known as ISIS, ahead of a larger terror attack planned for New Year’s Eve, according to reports.

Among the missions was visiting the campus of Ben Gurion University in Beersheba to determine if they could bring in a suitcase full of explosives for a bomb attack.
