According to a latest report, the world powers such as the United States and Germany are trying to figure out an agreement with Iran regarding the Islamic Republic's controversial nuclear program.

The world powers are striving to settle down and negotiate with Iran, in terms of nuclear parameters. The negotiation resumed in Geneva on Thursday.

The United States has recently entered the second formal round with Germany and other members of the United Nations Security Council. The other member countries include France, the United Kingdom, Russia and China.

The talks are being held in order to discuss the parameters of a temporary deal with Iran. According to the sources, the US is being particular about the fact, that the president Barack Obama should accept and approve the concerned deal with Iran.

White House spokesman Jay Carney said any sanctions, made on the table would be reversible. He also emphasized the deal would only move forward in case Iran offers concrete and verifiable measures in return.

Senator Robert Menendez, who is the chairman of the Foreign Relations Committee said, "What I do not understand is a negotiating posture in which we suspend our actions, we give them sanctions relief on existing sanctions, yet they continue to be able to enrich".
