Iran has asked the International Court of Justice (ICJ) to lift the sanctions imposed by the US after it abandoned the deal on Tehran’s nuclear programme.
Iranian lawyer Mohsen Mohebi said the US aimed to damage Iran’s economy “as severely as possible” and had violated a little-known 1955 friendship treaty.
The US said it would vigorously defend itself against the “meritless claim”.
Iran’s economy has slumped since US President Donald Trump ordered that the sanctions be reinstated in May.
The Iranian currency, the rial, has lost half its value against the dollar, the monthly inflation rate has risen to 10.2%, and unemployment stands at 12.5%.
On Sunday, Iran’s parliament voted to dismiss Finance Minister Masoud Karbasian over his failure to address the country’s economic woes.
