The first expelled extremist is a citizen of Tunisia, who has expressed support during imprisonment for the Daesh* terrorist group. The second one is a Gambian national, who has vowed to "kill white people" and Christians, according to the ministry.
The authorities have also expelled a 22-year-old Moroccan citizen, the ministry added.
