"The ruling is considered stealing the Islamic Republic of Iran's properties and naturally the onus of compensation of damages to Iran ... Falls on the US administration," foreign ministry spokesman Hossein Jaber Ansari said.
The spokesman said the decision went "against international law".
The Supreme Court ruled yesterday that Iran must hand over nearly USD 2 billion in frozen assets to survivors and relatives of those killed in attacks blamed on the Islamic republic.
The decision affects more than 1,000 Americans.
Justice Ruth Bader Ginsburg wrote the court's opinion rejecting the Iranian central bank's efforts to block payments to victims and relatives.
"We are extremely pleased with the Supreme Court's decision, which will bring long-overdue relief to more than 1,000 victims of Iranian terrorism and their families, many of whom have waited decades for redress," said Theodore Olson, a former US solicitor general who represented the relatives of the victims.
