Iran's foreign minister said in a U.S. television interview on Wednesday he believed "we are very close" to a nuclear deal with the six major world powers, but cautioned there were details that needed to be worked out.
Mohammad Javad Zarif says the West, especially the United States, must choose between reaching a nuclear deal with Iran or continuation of sanctions, as these two cannot go hand in hand.
In an exclusive interview with Press TV reporter in the Swiss city of Montreux on Wednesday, Zarif said if the West really seeks to reach an agreement with Iran over Tehran’s nuclear program, there is no need to continue with sanctions.
"We are prepared to work round the clock in order to reach an agreement," Mohammad Javad Zarif told NBC News in an interview excerpt released by the network.
In a speech to the U.S. Congress on Tuesday, Prime Minister Benjamin Netanyahu warned that the deal being negotiated was a serious mistake.

Iran’s Resident Representative to the IAEA, Ambassador Reza Najafi has regretted that a small portion of the latest IAEA report on Iran was “reappearance of the baseless past allegations on which our position is well known.” He said repetition of such “unfounded accusations” would not add to their value.
In a statement made before the Board of Governors in Vienna on Wednesday, Najafi said a recent revelation on manipulation of the evidences on the so-called “possible military dimension” testifies to the correctness of Iran’s statement and proves that all information and documents provided to the Agency on this issue are fabricated, IRNA reported.
Moreover “The IAEA and Iran have agreed to hold a technical meeting in Tehran on March 9, 2015,” the agency said in a statement on Wednesday, adding, and “The IAEA delegation will be headed by Tero Varjoranta, IAEA Deputy Director General and Head of the Department of Safeguards.”
The last technical meeting between the two sides was held in November last year.
On Monday, the IAEA once again verified lack of any diversion toward non-peaceful purposes in Iran’s declared nuclear material.
