The U.S. Court of Appeals for the Second Circuit on Wednesday threw out a lawsuit against Facebook by individuals who claimed the social networking site unlawfully provided a way for associates of Hamas, a fundamentalist group in the Middle East which has been designated by the U.S. government as a terrorist organization, to encourage acts of violence.

The litigation was brought by several persons who said they were either victims of attacks by Hamas and its supporters in Israel, or represented the estate of someone killed in an attack.
