Parliamentarians introduced a bill to oblige the government to demand compensation from the US for "its crimes against Iran and Iranian nationals".
Lawmaker Ebrahim Karkhanei, the main sponsor of the bill, told Fars News Agency on Saturday that 201 legislators have signed on to the proposal.
Karkhanei said the plan has been presented to the Majlis Presiding Board and will be brought to the floor this week.
The measure is in response to a US Supreme Court ruling that would transfer over $2 billion in frozen Iranian assets to the families of US soldiers killed in a 1983 attack on their barracks in Lebanon, among other attacks, that US courts have linked to Tehran. Iran has denied any role in the attacks.
"When the US Congress, government and courts use false and lousy excuses to take measures against Iranian interests, representatives of the nation should give a decisive response," he said.
The bill requires the government to claim compensation, or support the nationals who seek it, for the US measures against Tehran, including its involvement in the 1953 coup that overthrew the democratically elected government of then-prime minister Mohammad Mosaddeq and its support for former Iraqi dictator Saddam Hussein who imposed the 1980-88 war on Iran, in which hundreds of thousands of Iranian people were killed and injured.
On April 20, the US Supreme Court ruled that the US Congress did not usurp the authority of American courts by passing a 2012 law stating that the frozen funds should go toward satisfying a $2.65 billion judgment won by the families against Iran in US federal court in 2007.
Iranian officials have described the anti-Iran move a "theft" that violates Iran's state immunity and vowed to confront Washington's "bullying" and retrieve the money.
President Hassan Rouhani said last Tuesday Iran would soon lodge a complaint against the US with the International Court of Justice in The Hague, the Netherlands, over the move.
