Ahmed Aboutaleb, the mayor of Rotterdam, says he is upset about the Paris attacks as a democrat, a Muslim and a Moroccan. "There is a lot of confusion going on in my head. In my body, grief and anger fight with each other." According to him, the Brussels fitna was successful. The city has been gripped by terror and this is what terrorists aim for. "Fitna is stronger than war in the sense that it concerns a chaotic situation in which it is unknown where the danger is. You don't know who to and who not to trust."
