A jury on Wednesday convicted Hadi Matar on federal terrorism charges for the 2022 stabbing of author Salman Rushdie, who has faced a decades-old death threat over his novel "The Satanic Verses." Matar, 28, was found guilty of all counts, including engaging in an act of transnational terrorism and attempting to provide material support to the Lebanese militant group Hezbollah, according to the BBC. The SCMP reports that the conviction stems from the attack, which occurred in August 2022 in western New York. Matar is already serving a 25-year state prison sentence for attempted murder in the same stabbing. The federal charges carry additional penalties, including potential life imprisonment. During the trial, prosecutors argued that Matar targeted Rushdie because of the fatwa issued by Iran's Ayatollah Khomeini in 1989, which called for the author's death over his novel. Matar's lawyers did not immediately respond to a request for comment. This verdict marks the second conviction for Matar, who remains in custody.
