Negotiators from the U.S. House and Senate have reached agreement on a new round of sanctions against Iran.
The sanctions would target Iran's energy, shipping and insurance sectors with punitive measures aimed at derailing
Tehran's suspected push for nuclear weapons.
On July 30, a final bill was filed that expands on existing penalties.
The House of Representatives is expected to vote on the bill as soon as August 1. Congress has a week to go before its month-long August recess.
Senator Tim Johnson (Democrat-South Dakota), chairman of the Senate Banking Committee, said the bill reconciles proposals by the House and Senate.
He says unless the Iranians "come clean on their nuclear program, end the suppression of their people, and stop supporting terrorist activities," they will be increasingly isolated while facing "greater economic and diplomatic pressure."
