The lawsuit accuses Facebook of helping Palestinian group Hamas recruit members, communicate, plan attacks. The U.S. government designated Hamas a terrorist organization in 1995. Facebook didn’t comment directly on the lawsuit but said it doesn’t want violent messages on its website. Facebook users who see violent messages should report it so the company can “investigate and take swift action,” Facebook says. The lawsuit was brought under the Anti-Terrorism Act of 1992, which prohibits businesses from providing material support to designated terrorist groups.”]
