Relatives of Marines killed in an attack in Lebanon in 1983 want federal authorities to give them a Midtown skyscraper owned by a nonprofit organization accused of being a "front for the Iranian government." According to the Post, families of the 241 soldiers killed in the bombing of military barracks want 650 Fifth Avenue to serve as their compensation for the $2.6 billion in damages awarded to them in court three years ago. Federal prosecutors have tried to revoke ownership of the 36-story tower because the Alavi Foundation, which owns the building, has been accused of sending money to Iran despite a trade ban.
