The Supreme Court said Monday it will hear two cases seeking to hold social media companies financially responsible for terrorist attacks. Relatives of people killed in terror attacks in France and Turkey had sued Google, Twitter and Facebook, accusing the companies of helping terrorists spread their message and radicalize new recruits.

The court will hear the cases this term, which began Monday, with a decision expected before the court recesses for the summer, usually in late June. The court did not say when it would hear arguments, but the court has already filled its argument calendar for October and November.

One of the cases the justices will hear involves Nohemi Gonzalez, a 23-year-old U.S. citizen studying in Paris. The Cal State Long Beach student was one of 130 people killed in ISIS attacks in November 2015. The attackers struck cafes, outside the French national stadium and inside the Bataclan theater. Gonzalez died in an attack at La Belle Equipe bistro.
