According to its’ annual report, the Dutch Secret Security Service (AIVD) prevented several (terrorist) attacks, that where in different phases of preparation. AVID has done extensive research on jihadis that decide to stay home, instead of travelling abroad. But also on those that do decide to leave the country. Especially the increase number of women that travel to the Caliphate is a cause of serious concerns. It is estimated that they form around 25% of the total group that has left the Netherlands. Besides that, more often whole families try to leave for the caliphate and around 30 children have left the country.
