New York, Jun 16 :  The father of a young woman killed in the Paris massacre last November is suing Google, Facebook and Twitter, claiming that the companies provided “material support” to extremists in violation of the law. Reynaldo Gonzalez, whose daughter Nohemi was among 130 people killed in the Paris attacks, filed the suit on Tuesday in the US District Court in the Northern District of California. The suit claims the companies “knowingly permitted” the Islamic State group, referred to in the complaint as “ISIS,” to recruit members, raise money and spread “extremist propaganda” via their social-media services.

The Gonzalez suit is very similar to a case brought against Twitter in January by the widow of a contractor killed in an attack in Jordan. It includes numerous identical passages and screenshots, although the lawyers in the cases are different. In statements, Facebook and Twitter said yesterday the Gonzalez lawsuit is without merit, and all three companies cited their policies against extremist material. Twitter, for instance, said that it has “teams around the world actively investigating reports of rule violations, identifying violating conduct, and working with law enforcement entities when appropriate.” (ALSO READ: Paris attacks suspect Salah Abdeslam extradited to France)

Facebook’s statement read, in part, that if the company sees “evidence of a threat of imminent harm or a terror attack, we reach out to law enforcement.” Google, meanwhile, said it won’t comment on pending litigation, but noted that that it has “clear policies prohibiting terrorist recruitment and content intending to incite violence and quickly remove videos violating these policies when flagged by our users.”

Under US law, internet companies are generally exempt from liability for the material users post on their networks. Section 230 of the 1996 Communications Decency Act provides a legal “safe harbor” for companies like Twitter and Facebook; it states that “no provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider.”
