U.S. Supreme Court lets Twitter off hook in terrorism lawsuit over Istanbul massacre

The U.S. Supreme Court on Thursday refused to clear a path for victims of attacks by militant organizations to hold social media companies liable under a federal anti-terrorism law for failing to prevent the groups from using their platforms, handing a victory to Twitter Inc.

The justices, in a unanimous decision, reversed a lower court's ruling that had revived a lawsuit against Twitter by the American relatives of Nawras Alassaf, a Jordanian man killed in a 2017 attack during New Year's celebration in a Istanbul nightclub claimed by the Islamic State militant group.
