The families of two victims of Islamic State (“ISIS”) terror attacks in Paris and Brussels filed a groundbreaking antiterrorism lawsuit in January 2017 against the social media company TWITTER, INC. (“Twitter”), for its role in aiding and abetting the terrorist organization that carried out mass-casualty attacks in Paris and Brussels, killing nearly two hundred people and injuring hundreds more.

According to the families attorney, Nitsana Darshan-Leitner, director of Shurat HaDin-Israel Law Center: “This is the first lawsuit to document Twitter’s key role in the rise of ISIS to become the most feared terrorist organization in the world, and to detail how ISIS used Twitter specifically in connection with two of the worst terror attacks in Europe’s recent history. Among social media platforms, Twitter has most brazenly refused to cut off its services to terrorists, taking the position that ‘the tweets must flow’ even if it means assisting in mass murders.”

The lawsuit, which was filed in the U.S. District Court for the Southern District of New York, seeks compensation and punitive damages related to the deaths of victims of terrorist attacks carried out by ISIS, known as one of the most brutal terrorist organizations in the world.
