Iran's key representatives led by its atomic energy agency head, Mohammad Javad Zarif and President Hassan Rouhani's brother, Hossein Fereidoun were present in Vienna on Tuesday to continue discussions with other world diplomats including U.S. Secretary of State John Kerry.
Parties agreed that the June 30 would not to be met but discussion would proceed, according to BBC.
The diplomats from the U.K., France, China, Russia, U.S. and Germany will have time to hammer down the details of an accord, which primarily aims to have Iran agree to scale back its nuclear activities ensuring the world that it could not build a nuclear weapon.
The President of the United States has until July 9 to submit the details of the accord to Congress, which could entail a 30-day review period before it could be signed and any US sanctions lifted. If a deal is submitted after 9 July, the review period will be doubled to 60 days.
The U.S. and Iran together with all the countries involved in the discussions have committed to a diplomatic resolution, there were still pronouncements that military action would be an option if all else fails, CNN said in a related report.
In April, Defense Secretary Ashton Carter told CNN's Erin Burnett that while the U.S. is keen on the diplomatic talks, it is prepared to tap other unnecessary options such as the use of the bomber-busting bomb known as the Massive Ordnance Penetrator (MOP) – a 15-ton behemoth that can explode 200 feet underground and is designed specifically to destroy deeply buried and fortified targets.
Carter said the U.S. would not hesitate to use its capability to shut down the Iranian nuclear program for good.
