US Republicans said Tuesday they were introducing legislation that would use frozen Iranian assets to pay American victims of Iranian terrorism before billions of dollars are returned to Tehran as part of the nuclear deal, AFP reports.

Congressional Republicans are furious over President Barack Obama's landmark accord with world powers that aims to rein in Iran's nuclear program, in exchange for an easing of sanctions that have crippled the Islamic republic's economy. They see the Justice for Victims of Iranian Terrorism Act as a way to stall the deal, or at least take a major bite out of funds that would be returned to Tehran.

The bill will be introduced this week, according to its sponsor, House Republican Pat Meehan.
