"Germany and Austria should definitely take those threats very seriously, unfortunately we have seen that those kind of threats are often followed by real terrorist attacks, so we cannot afford not to strengthen our national security, also by using the army to patrol at vital infrastructure all over Europe," Geert Wilders told Sputnik.
In the video, the militants also call on Austrian and German Muslims to join ISIL at the territories under the group’s control.
Moreover, the footage shows the militants executing two captives.
ISIL has occupied large areas in Syria and Iraq. The militants are notorious for multiple human rights atrocities, including executions of religious minorities and foreign hostages.
Over 720 militants, most below the age of 30, have left Germany to join Islamic State, according to July estimates by the Federal Office for the Protection of the Constitution (BfV).
