In a landmark ruling in the Danish Supreme Court,a Danish-born ISIS terrorist has had his citizenship revoked.

 Enes Ciftci, a Danish-Turkish citizen, was sentenced to six years imprisonment, permanent expulsion from Denmark and revocation of his citizenship for fighting with the Islamic State in Syria.

The case marks the first time citizenship has been revoked from someone who was born and raised in Denmark and could pave the way for expulsions all across Europe.

The Danish High Court ruled originally that he should lose his citizenship and be expelled from the country forever and the  decision was backed by the Supreme Court.
