The Security Service believes this information to be sufficient grounds for the creation of a unified database on children who came back to the Netherlands from territories controlled by Daesh.
Each child will be given a unique registration number. The information base will also be available to intelligence services of other European countries.
At a recent conference in Berlin, the head of the Dutch intelligence service said that the authorities are aware of 70 minors who left the Netherlands and headed to Syria and Iraq.
Daesh, which is outlawed in Russia and a number of other countries, has taken over large territories of Syria and Iraq, including a vast part of Anbar province, since 2014, declaring a caliphate on the territories under its control and committing numerous human rights atrocities.
