US prosecutors unveiled plans Thursday to sell an Iran-owned Manhattan skyscraper in the largest terror-related seizure ever, and distribute proceeds to families affected by attacks linked to Tehran.

Among the creditors are families and estates of victims of the 1983 bombings of US Marine barracks in Beirut that killed 241 military personnel and the 1996 bombing of the Khobar Towers in Saudi Arabia that killed 19 US service members.

No date has yet been set for the sale of the properties, and one private plaintiff has not joined the settlement.
