Iran has filed a lawsuit with the International Court of Justice to recover $2 billion worth of frozen assets the U.S. Supreme Court awarded to victims of a 1983 bombing in Lebanon and other attacks linked to Iran.
In remarks broadcast Wednesday on state TV, President Hassan Rouhani said the claim had been filed the day before.
The Supreme Court ruling, issued in April, directly affects more than 1,300 relatives of victims, some who have been seeking compensation for more than 30 years. They include families of the 241 U.S. service members who died in the Beirut bombing.
Iran has denied any role in the attacks and rejected the court ruling, saying it amounted to theft.
It was not immediately clear whether the ICJ would have jurisdiction over the case.
