On 1 March 2016 the Dutch Senate accepted a bill that broadens the power of the Minster of Justice to withdraw Dutch citizenship from a person who has been convicted for facilitating a terrorist crime, unless this would render the person stateless. Concretely, a conviction pursuant to Article 134a of the Dutch Penal Code (in Dutch) has become an additional ground for loss under Article 14(2)b of the Dutch Citizenship Act. See here and here (in Dutch) 

A more far-reaching bill 34356 (R2064) (in Dutch) providing for the possibility of withdrawing Dutch citizenship from a person who voluntarily joins a terrorist organisation and without the need for a prior criminal conviction is still pending.
