The father of the girl who died during the terrorist attacks in Paris has filed a suit against Twitter, Google, and Facebook for "supporting” the propaganda of the Islamic State, reports the TMZ. Reynaldo Gonzalez, whose daughter Nohemi was killed by terrorists, believes that social networks allowed the IS to become the most deterrent terrorist group today.

The plaintiff accuses the social networks of negligence, since they allow terrorists to register and spread their extremist ideas. In addition, he suspects YouTube in making a revenue from advertising the militants.
