The U.N. Security Council on Monday unanimously endorsed the landmark nuclear deal between Iran and six world powers and authorized a series of measures leading to the end of U.N. sanctions that have hurt Iran's economy.

But the measure also provides a mechanism for U.N. sanctions to "snap back" in place if Iran fails to meet its obligations, ABC News reported on Monday.

The resolution had been agreed to by the five veto-wielding council members, who along with Germany negotiated the nuclear deal with Iran. It was co-sponsored by all 15 members of the Security Council.

Under the agreement, Iran's nuclear program will be curbed for a decade in exchange for potentially hundreds of billions of dollars' worth of relief from international sanctions. Many key penalties on the Iranian economy, such as those related to the energy and financial sectors, could be lifted by the end of the year.
